Nice room with a view of the water . Good service from friendly staff. They let us check in at 1000 which was wonderful after a long flight. Breakfast was amazing . The executive lounge had outstanding food and beverages. Elevators were a little odd to us at first but the system really does work well. Staff was helpful when we needed a cab and we found the public transportation easy to use and close by.

What a great hotel experience. From the clean, modern and spacious rooms, to the elite customer service, to the absolutely decadent breakfast to the utterly breathtaking pool, it was one of the best Hilton stays I've had. The customer service was unmatched, as they constantly strove to provide the best of the best service. The breakfast is a hidden gem, as you have omelets cooked to order, fresh batch of bacon, sausage and eggs. A whole table dedicated to fresh bread. Drink stations filtered throughout, coffee stations throughout and of course, for those who prefer the healthier options, a giant fruit, yogurt and deli section. Really, am amazing experience!

I like a hotel with a good Executive Lounge but am often disappointed with the offerings, this was one of the better lounges. A great array of food and drinks during my one night stay. Very friendly staff throughout the hotel and a comfortable room - I can ask for no more so would stay here in my next visit to Barcelona.

My wife and I loved staying at this hotel. We were put on the 13th floor and we had a fantastic view of the ocean. Our room was clean and had everything we needed. Bell staff were awesome in helping to park our car and bring our things to the room. Breakfast the next morning was very nice. Highly recommended when in Barcelona.

We highly recommend the Hilton Diagonal Mar. The service was excellent! We were very impressed with the quality of food and the incredible hospitality from the staff. The views of the sea from our room and the city from executive lounge were fantastic! Aürt and Mai were fantastic restaurants. While this hotel is a little further from the touristy areas, it was an easy metro ride to town. The metro was clean and reliable.
