I can only comment on Diagonal Mar. One night stay September 9 .
We stayed here for one night on our way back from Seville. We actually started our trip in Barcelona, but stayed elsewhere in town. I was well informed prior to my stay that the hotel is removed from the city, but accessible by metro, cab. This actually met our needs as we were flying home the next day. We took a cab from the Saints station. Fare was approximately 35 Euros. The beach is very close as well as a mall directly across the street. Note - Everything is closed on Sundays. There are a few restaurants open.

Check In:
Check In was very quick and efficient. No long queues. The associate was very friendly and reviewed all my Diamond VIP benefits. We had a King Sea view room booked, and informed that we were up-graded to the executive floor. If you’re staying on the executive level floors, you do need to use the key in the elevators. Lobby was bright and airy, several seating areas and a bar/restaurant.

Room:
King Executive Sea view, large windows with the best view of the sea. King Size bed, sitting area with small table and lounger, desk, drawer/shelving with flat screen T.V, 2 bottles of water (complimentary), tea/coffee with kettle. Bathroom was very large and spacious, ample space on vanity, bath/shower combo, toilet and bidet. A large closet with ample hangers, bathrobes and slippers. The hotel was kind enough to acknowledge a special occasion with a lovely bottle of Cava chilled on ice and desert waiting for us when we arrived. We had to call the front desk to complain about the volume of the TV in the room next to us. They immediately took care of the problem without hesitation. Our neighbor had left the volume up high, and was out for the evening. The room completely exceeded our expectations.

Executive Lounge:
Prior to arriving, I was well aware of the recent changes to the Executive lounge offerings. I had read reviews from other members commenting on their displeasure. The lounge is pretty large, with a great out door warp around patio. You almost have 180 degree view of the city. Some great photo opportunities. There is receptionist that you check in with and they will validate you have entry. We arrived around 2:30pm. Only soft drinks, tea/coffee, water, popcorn and crackers were available. The fridge with beer/wine/cava was locked up until 5pm. It wasn’t a problem for us, as we just wanted a quick cup of coffee. We returned for the evening happy hour (complimentary beer/wine/cava). I can’t recall if it was 5 or 5:30pm, but it’s only for 2 hours. In addition, there was one hot snack, and some small sandwiches. This is a big change from the executive lounges prior offerings, but honestly, it really met our needs. We’re not looking to eat our dinner there. Just to have a few glasses of a spirits and nibbles in a nice atmosphere. We had to leave rather early the next morning to leave for the airport. We chose to have breakfast in the lounge. It was more than sufficient. The typical Euro style with meats, cheese, bread and some hot items. I believe Diamonds may also elect to eat in the restaurant.

Restaurant:
We decided to have a little dinner. Service was excellent, a good variety of food on the menu. Kudos to David.

Check out was a breeze. Taxis are readily available. The bellman was very nice and quickly assisted me with my luggage despite me saying it was ok.
This hotel was perfect for us for one night. I’m not sure I would stay here for my entire time in Barcelona. For us, we like to me closer to the main sights and restaurants. Everyone is different. I would have no problem returning her or recommending it to anyone.
A solid choice.
