Really comfy beds and clean apartment! The location of the apt is really good for a short city trip - as we did. Ricardo was a very welcoming and friendly host! Everything was perfect. The only aspect that could be criticized is that the walls are quite thin - you can hear your neighbors and the street a little bit. But still a great accommodation and worth a stay.
Also: try the "Confiteria Imperial" on the other side of the road (a bit right towards the metro station Sao Sebastiao) - they have amazing pastries!!
