Had a very comfortable 1-week stay at Joao & Filipa's place. Filipa was at the apartment to meet us and she was very kind in accommodating our check-in. The location of the apartment is amazing, very close to metro station and right in the middle of everything. Some of the small details I appreciated included the variety of tea and coffee, a power adapter in the bedroom useful for North American outlets and I felt very secure in the apartment. I would highly recommend Joao and Filipa's place for your stay in Lisbon.
