Great appartment with nice views from the two Terraces, the appartment has a good size, is bright and nicely furnished. The location with proximity to Sagrada Familia is well-connected and convenient. The Wifi was a bit on and off and there was a weird smell coming from the bathroom.
However, the non-flexibility regarding the check-in is a big minus. Check-in after 11pm is not possible, which was problematic for us due to late flights (that were further delayed). Manuel was not flexible or helpful here and asked us to either cancel the appartment at our own cost or send a friend to pick up the keys. In the end, we managed to mobilise someone to pick up the keys for us and enjoyed our stay at the appartment, but the discussions with Manuel beforehand about the check-in and the communication in general (he kept sending standardised messages regularly that did not fit the rest of the conversation) threw us off beforehand. Only book with him if you are sure that you can comply with his check-in times.
