Hotel Sixties had incredibly friendly staff who were all to some degree multilingual and extremely accommodating. the rooms were clean, comfortable, and had good air conditioning. The bathrooms were especially very nice. since it is a hotel, they have daily room service that does a great job as well. At one point, when an outtage caused the Air Conditioning to go out temporarily for a day, they were polite enough to even give us a room change, free of charge. I would absolutely come back to this hotel if I were to ever stay again in Barcelona!
