The room is very comfortable and clean - the bathroom too.
It's not very quiet place. The window faces the yard that is surrounded on all sides by buildings and that makes every sound louder. When people from other buildings are eating, partying or shouting until late at night, it can be very noisy.
The host didn't inform us before that in the flat live permament residents. They are very nice but can be noisy, for example when they start to cook and sing early in the morning or they play loud music during the night. But when you talk with them, they understand and everything is fine. They also seem not to ventilate their room and the not so nice smell is felt all over the place.
The big problem was the organizational side of the accommodation. It's difficult to find the right flat. Neither Margarida, nor Felipe let us into the apartment. I got the number to Cristina that supposed to let us in, but couldn't contact her, because it turned out that it was the number of other worker of the hosts. Then I got another number and it turned out to be the number to another worker.
There is no air conditioner but it's usually really chilly at the balcony.
The big advantage of the apartment is the localization - two metro stations, many shops and restaurants (I recommend especially Nepalese restaurant "Namaste", R. Francisco Sanches 140 142).
