We spent 4 great days at Rodrigos apartment. It was perfectly for the two of us, but would easily fit one or two kids.
The apartment was very clean, with nice furniture and a comfortable bed.
The location was perfect to explore the city, only a 10 minutes walk to Santa Catarina or Bairro alto. There are severall tram, bus and train stations around the corner.
At night the street is very quiet, we even could sleep with the windows wide open.
Definitly a recommendation!
