We enjoyed our stay at Teresa's place. It was a pleasure to have a breakfast sitting on the terrasse and enjoying beautiful view over Lisbon. The apartment itself is very cosy, recently renovated and it has everything we needed. The neighbourhood is residential and there is not so much to do. Rua da Graça where you can find supermarkets and a very good bakery is within 10 minutes walk. The city center is within walking distance and there are several bus stops nearby as well.
I would recommend Teresa's place, especially if you like to live outside of touristy areas.
