Downsides: The house is tiny, and not the best for cold winter days (only 1 heater for 3 spaces, Célia offered to look for another, but we were already halfway and survived so we declined). We were also not very fond of a bathroom without window, no way to air the room, and the shower floods easily, so a little inconvenient.
Plus:
Location was good: shops and veggie restaurant nearby, close to Magoito beach, not too far from Sintra.
Double plus: Célia is a very kind person! She was very fast and perfect in her communication to us. She did her best to make sure everything was fine, brought baby chair.
