We stayed at Sergio's place and for us it was a bit far out from the centre of the city, and we had to get a bus (which wasn't very frequent). It was relatively clean, and the beds were relatively comfortable. The room was exactly like the pictures.
We needed to check in earlier than the 5pm time and the host was kind enough to let us leave our bags earlier and collect our keys, and communicated well with us.
Our stay was mostly disrupted by other guests in the other room who came back to the apartment at 4.30am and were extremely loud, which wasn't pleasant!
But overall its a good room to stay in for a night or two if you're staying in the neighbourhood.
