The apartment was even nicer than it looked in the pictures. It was clean, had a beautiful view, is big enough for 1/2 persons. The issues mentioned in the previous comments with the bathroom drain had been fixed, I faced no problems. Inside the apartment building there is a renovation going on with the stairs, but it wasn’t disturbing- just need to be a bit careful with your steps.
Rui was helpful and responsive. He replied to every request with attention.
The area is very nice and really in the middle of the Thieves Market. To Bairro Alto or such central locations, it takes a bit of a walk (at least 30 mins).
