My daughter stayed in Rodrigo's apartment for 5 nights, and would definitely stay here on a future trip. The apartment is clean, comfortable and has everything you need for a city break. Rodrigo was very friendly and helpful when she arrived, suggesting places in the city she could visit, and providing an overview of the neighbourhood.
The apartment is located in a quiet and safe neighbourhood with plenty of bars, cafes and restaurants on the doorstep. She suggests Heim Cafe for breakfast or brunch, Clube de Journalistas and Osteria (on Rua das Madres) for dinner. There is also a tram stop for the 25 tram 5 minutes walk away, and you're a short walk to several bus stops and Santos train station.
Definitely take Rodrigo's advice and get a taxi or Uber from the airport with your luggage - the main street is very steep and really not designed for dragging luggage!"
