Nice and cozy apartment in city center, just few meters away from Sagrada Familia, some good restaurants nearby, metro is also few meters away. The apartment is small, but we were 5 of us staying there and it was big enough. It seems it was completely renovated few months ago, will recomend to anyone traveling to Barcelona.
If I could change something, that would be: Better wifi, because it wasn't working well, it has speed around 1Mb, so it was unable to use it if we were 5 of us together connected. Windows are pretty old, so they didn't seal well, we heard a lot of noise from outside, it would be also better if there will be some curtains.
