We had a good stay at this place, it is simple but great if you don't intend to stick around the apartment. Sónia was working where we arrived so one of her friends greeted us. She was very nice and gave us a long list of things to do around town and a couple of restaurants in the area to try. Sónia always answered back very rapidly when we exchanged over AirBnB and texted us every 2-3 days to make sure that everything was going ok on our side.
The location is about 15 minutes from downtown by foot, but has a lot of hip cafés and good restaurants nearby. It is also only a 10-15 min walk to the Santos train station which accesses Belem and the Cascais beaches.
