Hilton Diagonal Mar Barcelona

General Overview

Hilton Diagonal Mar Barcelona is a four-star conference hotel in Barcelona, Spain, with a substantial meetings and events operation. The hotel has 433 guestrooms and suites, 22 meeting rooms and a 1,000 sqm pillar-free ballroom. Its facilities support corporate, association, healthcare and life sciences events, ranging from executive-level meetings and advisory boards to larger conferences of up to 1,000 delegates in theatre style.

The hotel is located adjacent to the Barcelona International Convention Centre (CCIB), allowing it to support standalone meetings as well as events associated with larger congresses. Its accommodation, meeting facilities and event catering provision enable organisers to deliver residential and multi-day programmes at one venue.

Location

Hilton Diagonal Mar Barcelona is located in Barcelona's modern business district, adjacent to the Barcelona International Convention Centre (CCIB).  The surrounding area is described as a business and innovation district rather than a historic city-centre setting. The hotel is within walking distance of the CCIB, making it particularly relevant for organisers attending or supporting events at the convention centre.

Barcelona-El Prat Airport is approximately 25 minutes from the hotel, and has direct access to Metro Line 4 via El Maresme | Fòrum station, with tram and bus connections nearby. 

The hotel provides on-site parking and coach access for group arrivals and departures. 

Design

Hilton Diagonal Mar Barcelona has a contemporary interior design that incorporates references to Barcelona's architectural heritage and creative culture. The venue profile identifies the use of design elements inspired by Antoni Gaudí's Trencadís mosaic technique, alongside contemporary materials, natural tones and locally inspired artwork. The stated approach combines destination-related design features with a functional environment for meetings and events.

The meeting facilities include flexible rooms, spacious foyers and light-filled public areas. These areas support registration, networking, hospitality welcome points, event branding and poster displays. The layout is intended to facilitate delegate movement between plenary sessions, breakout meetings and catering areas.

Meeting Spaces

The hotel has 22 flexible meeting rooms across two dedicated event levels, with a total conference and event offering centred on a 1,000 sqm pillar-free ballroom. The ballroom accommodates up to 1,000 delegates in theatre style, 800 in classroom style and 600 in cabaret style. It can be divided into smaller sections to support different event formats and programme requirements.

The ballroom, main plenary space and registration area are located on the same level as the hotel lobby. Most of the remaining meeting rooms and boardrooms are situated on the level above and can be reached by escalators and lifts. 

The meeting facilities can support plenary sessions, educational programmes, committee meetings, advisory boards and concurrent breakout sessions. Spacious foyers can be used for registration desks, hospitality welcome areas, event branding, sponsor visibility and poster displays. Several meeting-room clusters and event areas can be privatised for exclusive use, subject to confirmation with the hotel.

A dedicated in-house audiovisual partner supports in-person and hybrid events. 

Bedrooms

Hilton Diagonal Mar Barcelona has 433 guestrooms and suites across 21 guest-room floors. The supplied profile identifies three broad categories for venue listing purposes: Standard Rooms, Executive Rooms and Suites. 

Guestrooms start at 31 sqm and are designed to accommodate business travellers. The facilities include a dedicated work desk, complimentary Wi-Fi, laptop-size safe, tea and coffee-making facilities, air conditioning, HDTV, iron and ironing board, and an empty mini-fridge.

Restaurant and Public Spaces

Hilton Diagonal Mar Barcelona offers catering solutions that can be integrated into meeting and event programmes. For conferences and larger healthcare meetings, catering is commonly delivered within the dedicated event areas. Foyers adjacent to meeting rooms can accommodate standing buffet lunches, refreshment breaks and networking sessions, while the ballroom can be used for seated buffet lunches and larger group dining functions.

The Indigo Restaurant, located on Level 1, serves Mediterranean and international cuisine and accommodates approximately 170 guests. The restaurant can be reserved for private group lunches and dinners when required. The hotel states that its culinary team can provide coffee breaks, standing buffet lunches, seated buffet lunches, group dinners and cocktail receptions. Dietary requirements including vegetarian, vegan, gluten-free and allergy-conscious menus can be accommodated.

The hotel offers the GlassHouse, a 550 sqm outdoor event space, and the Purobeach Terrace as options for private lunches, dinners and receptions. 

Experience

Hilton Diagonal Mar Barcelona has extensive experience hosting healthcare and life sciences meetings including investigator meetings, advisory boards, medical education programmes, training workshops and congress-associated events. The hotel also works regularly with global healthcare and life sciences organisations, specialist healthcare agencies and professional congress organisers.

Fitness

The hotel operates a fitness centre equipped with cardiovascular and strength-training equipment. A seasonal outdoor swimming pool is also available but does not operate a spa and does not position itself as a wellness destination. The fitness centre and pool are located separately from the meeting and conference areas, providing a distinction between event facilities and guest leisure amenities.

Hilton Diagonal Mar Barcelona is an officially classified 4-star hotel and positions itself primarily as a meetings and events venue serving corporate, association and healthcare groups.

The hotel benefits from a strategic location adjacent to the Barcelona International Convention Centre (CCIB) and within Barcelona's innovation district, providing convenient access to leading hospitals, research centres, universities and life sciences organisations.

While the hotel offers guest amenities including fitness facilities and seasonal outdoor leisure areas, its healthcare proposition is centred on professional event delivery, operational expertise and extensive experience hosting healthcare and life sciences meetings.

From a healthcare compliance perspective, meetings and events represent a core part of the hotel's business, supported by dedicated conference facilities, extensive experience working with healthcare organisations and a strong understanding of industry requirements.

As part of Hilton, the hotel benefits from the company's global sustainability program, LightStay, which measures and manages environmental and social impact across the portfolio. Through LightStay, Hilton tracks key sustainability metrics including energy consumption, water use, waste management and carbon emissions, supporting responsible hotel operations and sustainable event delivery.

In addition, Hilton Diagonal Mar Barcelona operates under Hilton's global brand standards and processes, providing a professional and reliable environment for healthcare and life sciences meetings. The hotel regularly hosts a wide range of healthcare-related events, from small advisory boards and investigator meetings to larger congress-related gatherings, demonstrating its experience in supporting the specific needs of the sector.

These strengths, combined with Hilton's global network, sustainability commitment and extensive meetings expertise, make Hilton Diagonal Mar Barcelona a suitable partner for healthcare and life sciences organisations seeking a professional, compliant and service-focused venue.
