Great hotel in Eixample district, not much to complain about. Rooms against backyard is totally quiet, Aircon is as well silent. In std room it’s limited to 24*C, but not a problem. Rooms towards street on lower floors can hear some noise, we had room on 2nd floor, but we slept well.
I can only recommend this hotel, one of the best in Barcelona. Only problem would be distance to metro, but If your fine with Taxis book this, 5-10 min ride to anything worth seeing since it’s in the middle. Walking distance to best food district and shopping,
