This apartment is located at the heart of Campo de Ourique - we rented the apartment for my mother-in-law while she visited us in Lisbon.
The apartment is recently renovated, in great shape and super functional. The 2 bedrooms in the back are smaller but very quiet. The bedroom in the front is larger but the windows give to the street so it's a bit more noisy - Campo de Ourique is quiet at night, so not a big issue. The apartment is on the ground floor (or a half a floor up), but nonetheless it feels private. The AC worked fantastically - we had a few days of 35ºC which is atypical for Lisbon, and the AC saved us from the heat!
Communication with the hosts was fast, and they were flexible with the check in times which was a big plus for us. Recommended stay!
