The entrance to the hotel is very impressive but the check-in was a slow and dismal experience, no welcoming smiles just a long wait while our reservations and passports were checked from cover to cover. I am currently a Hilton diamond member and we were upgraded to a room on a high floor with a sea view - whilst we could see the sea the outlook is mainly office blocks, the motorway to the city, and the car park. I'm glad I didn't pay for the view!
As a diamond member, we had access to the Exec Lounge. A relatively small lounge given the size of the hotel, hence it was frequently overcrowded - at peak hours there was a queue for seating.
The exec lounge breakfast was poor for a Hilton, very limited choice of hot or cold food and cheap machine coffee. It was so bad we only went a couple of times. In the evening the lounge provided FOUR hours of free drinks - although people were sensible this meant the rather sterile lounge was the busiest place in the hotel. No wonder the main bar was always empty. We had a late drink in the bar one evening$and felt sorry for David - great bar tender, welcoming, informative, great cocktails, but no customers. Why no customers - the prices - wow! The Hilton bar is three times the price of all surrounding bars, and there are many to choose from in the neighbouring streets.
The positives about the hotel - the pool and gym areas of the hotel are new and kept to a high standard. The location is probably not for everyone being at the Northern most reaches of the beach, but you can walk along the beach to the main city beaches in under an hour, The hotel is also close to PobleNou which has a great selection of bars and restaurants within walking distance of the hotel.
In summary - I don't think the hotel is worth the premium price tag. In my opinion the other Barcelona Hilton is a nicer hotel and much better value, I'd recommend staying there and getting a cab to/from the beach.
