We had a nice stay at Jose's apartment. Check-in was flexible. We did not get to meet him because an associate let us into the apartment, but he always communicated quickly.
The apartment is in a convenient area, not particularly interesting on its own, but close to the train station and to the historic center as well. We were there on the weekend before the Semana de Las Fallas. There was a party tent with loud music on the street, so we needed earplugs to sleep on Saturday night, but in general I would think that the street is very quiet.
The apartment looks as shown in the pictures and had everything we needed for our stay.
