Great apartment, everything was as pictured. Unit is located on the 3rd floor (top floor) of a small apartment building and is modernly decorated. There is also an elevator in the building. Lots of Juliette balconies in the living room which provide plenty of natural light complete with black out shutters when you want to get some sleep. There is also air conditioning in the living room and bedroom. Apartment is located on a quiet street, yet is still very easy to find as it is in a central location, it's really a beautiful neighbourhood.
From Lisbon airport we took an uber which took around 20-30min and cost us €8. There's plenty of restaurants, bakeries and beautiful vistas all within walking distance.
Communication with Filipe after booking was a little bit slow but we realized it's because his apartment is managed by a rental company. The check in was a very quick and brief process. Someone from the rental company will meet you at the apartment to exchange keys and take passport info. Be prepared in having done your own research of the area and on places to go since they didn't have the time to walk us through a map or things to do, recommendations etc. We were prepared and mapped things out around the area beforehand. When we checked out, the rental company was helpful in offering us a place to store our luggage.
All in all this place was great and we will definitely stay here again the next time we visit.
