Unfortunately never got to meet Luís but I was greeted by a Brazilian lady who showed me around the apartment and showed me “suggestion” book around Portugal. The only text communication with Luis I had was when I booked the apartment and when I left to explain where to leave the keys, and he was very forthcoming with me leaving my suitcase in the corridor until I left for the airport.
The apartment was really bright and clean, exactly as in the pictures.
The sound on the streets was a bit of an issue and while the windows and shutters were good to shut out the outside noise, the building is an old wooden house and there is a bar/live music club right underneath it, so the disco sounds could be heard through the floor. However if you sleep like a baby or like to be up late that should not be a problem.
