The hotel is conveniently located in very short walking distance to the metro stop Diagonal, which allows access to the airport (1 change only) and to 3 metro lines. The Sagrada Familia is just 2 stops away. Casa Pedrera and Batillò are 2 mins walk away. One can reach Plaza de Catalunya very easily, about 10 mins walk away. The area is full of high quality shops, if you are interested in shopping.
The hotel is welcoming, the staff all very professional and smiling, the room was clean, super quiet, with an AC that does its job well. The windows can be opened freely (a rarity in modern hotels) to let nice fresh air in if so desired.
Free wifi offers very respectable 40Mbit Up-/Downlink speeds and perfect reception (at least in our room).
A Nespresso machine is available in the room, which is always a nice touch, as well as a water boiler and a full mini-bar.
Breakfast is really good and offers quality ingredients: it is well worth the price.
We had dinner twice in the hotel's Sintonia restaurant (were also breakfast is served) as it was so good the first time, we had to try it again. Not only the staff is very good and the atmosphere is welcoming and quiet, but food was just amazing as well as the cocktails. Try it at least once.
Unfortunately the weather was not good enough to use the roof pool (not big, but enough for a nice refreshing dip) next to the rooftop bar.
If I were to go back to Barcelona I would book this hotel again. A keeper.
