Damien's flat is very nice: it's central, safe, clean and has a great terrace.
We were 2 friends so we each slept in a different room.
The flat can easily hosts 4 people, so we had a nice space just for us. It is not very modern, but then again it's in fair condition. The area is amazing and there are lots of cafes, restaurants and supermarkets just a minute walk from home.
I would stay there again when I'm in Barcelona next.
