I would not stay here again. Actually, I wanted to leave when we saw our room. We flew into Barcelona at night. There was a note at the door for us to go to their other location Brustar Centric. When we got their the receptionist was leaving for the night. She said they had emailed us earlier that day to not only change our hotel (without consent), but that they have limited administration time (10am-10pm). If we had not run into her, we would not have been able to get inside the building, nor into our room for the night.
The room is small, but I really questioned the cleanliness. We were only given one towel for two people, so we had to share a towel since we couldn't call anyone for another. The hotel in itself is super old. I normally don't mind older buildings as long as there is maintenance.
Our second day there was a power outage. I guess this happens often since there is a sign that says to not use anything (sink, shower, toilet). Reception didn't open until 10am and we needed to get ready for a tour, so we ended up using moist towelettes we brought for a "quick shower." When we came back we realized that the towels we placed onto the floor to be changed out was hung back into the rack (to be used again). For the 4 days we stayed there, our towels were never changed out. I could only imagine how the sheets are never washed. The only thing good about this place is it's location. I would say it's centrally located. Everywhere we went was within walking distance.
