We enjoyed our stay at Sonia's flat. The location is perfect. There are so many wonderful cafes & restaurants, we loved wandering the streets and soaking in all of Lisbon's charm. Tram 28 stops right in front of the apartment. There are 3 good grocery stores within 5 minute walk (2 just around the corner). For longer stays, this was really convenient. Sonia's apartment also has a desk, an absolute rarity in airbnb apartments, and as digital nomads this was very much appreciated.
The flat is a little worn, but it's also charming. Sonia has a lot of great furniture and decor - this is not the run of the mill Ikea furnished apartment. During winter months it can be a little cold and dark (but this seems to be the case for all Lisbon apartments?) but Sonia provided two heaters. For longer stays during the colder months, drying clothes can be a bit challenging - but there is a laundromat across the street and one around the corner.
The location cannot be beat!
