We enjoyed staying here. The apartment has a bit of a strange floorplan with bedrooms on opposite sides, but it actually worked very well for us because it provided some privacy and isolation.
The place is very clean and because we stayed for a week, the hosts came and did a thorough cleaning in the middle of the stay. It's very nicely furbished and decorated.
Check-in was very easy, we were met at the apartment by Carina who showed us everything and even gave a brief overview of Lisbon and places to visit. She also gave us recommendations of supermarkets, transport, and restaurants. We got early check-in for a small fee, which was nice after a red-eye flight.
Location is OK. It's about 10-15 min brisk walk to the closest subway and train station. Tram 28 stops nearby. The street is not very busy, although there was some rowdiness at night on weekends. Two bedrooms face the street and it got loud a couple of times, but not too bad. One bedroom faces inner garden and is very quiet.
