Anna's apartment is nice, and the terrace is a big plus! The area is both interesting and fun. It is fairly easy to get to any place you want if you walk 10 min to the subway station.
Although it was mentioned by some of the earlier guests, it is not mentioned in the description that there is a bar right below. We didn't hear much of what was going on INSIDE the bar, but there was always people outside the bar smoking and talking. With the narrow space between the buildings, this was quite loud. And it lasted usually until around 4:30 in the morning.
I don't think this apartment is very well suited for people with children who prefers quiet nights, but it is well suited for couples or friends who want to explore BCN's social life.
