Graça is a very welcoming and helpful host. Her place looks like the pictures - location is fairly convenient for town/sight seeing, and is definitely convenient for the airport. There are plenty of amenities close by and transport around Lisbon is very easy.
We were there in January so perhaps to do with the weather, but it felt slightly damp inside despite the electric heaters being on all of the time. Incidentally, the wiring is slightly dodgy and the circuit tripped out a couple of times…!
Take ear plugs for the night time if you need quiet to sleep - 2 of the bedrooms are adjacent to the road, so you hear everyone/thing outside, and any noise from the upstairs flats and particularly the main door when people come and go. The pharmacy on the corner sells ear plugs if you get stuck!
Very well equipped kitchen with regard to appliances, and she leaves tea and coffee for you too which we were grateful for!
