We had such a fantastic stay in João's great apartment. It is located in the perfect position in the middle of everything, yet it is quiet and tucked away. Everywhere is walkable but be prepared for the hills of Lisbon, they keep you very fit!
The apartment itself is super clean and light and being on the top floor gives you great views over the city, particularly from the bedroom looking east towards Castilo and Mouraria.
We absolutely loved Lisbon and it was made even better by coming home to this apartment each night, thank you João!
