João is THE perfect host, he gave us very nice tips on the city and he was always available on Whatsapp.
The apartment is small but really nice and cozy, just next to São Bento station and 1 minute walk from Rua Dos Flores.
The road to get there is very steep therefore I recommend it for backpackers.
The only negative feature is the tiny bathroom and shower, they were not very comfortable although they were perfectly clean.
