Everything was fine, it was clean and really close to Sagrada (5 min walk) and the subway, also close to the main attractions. It was quiet with the windows closed and we slept just fine (Barcelona is a noisy city, so this was what we were looking for). The communication with the host was good, he made sure we had everything that we needed and answered to any question we had. On the other side, the place was much smaller than we expected, it smelled like mold in the beginning, before we opened the windows and the price seemed a little bit high, but Barcelona is an expensive city anyway and the central position made it worth it in the end; after letting a lot of air come in, it was fine. We also liked that the building was safe and only the people with the key could get in. All in all, it was a good experience, it was quiet at night, we had everything we needed and the position certainly helped save some time!
