This place has great reviews for a reason. It is really special. I stayed here for 5 nights and I really loved it. It was like a home for me. Very cozy but plenty of space, magnificent views of Lisbon, great kitchen amenities, comfortable mattresses - it has it all.
The owners are extremely reach-able. Goncalo took the time to show me the place and checked in to make sure everything was fine, as well as sending tips / suggestions on sights to see and places to eat. The apartment is in a safe, charming and historical part of the city. I really loved the apartment and would like to stay here again if I return to Lisbon.
