I definitely suggest to stay at Yves's place.
Just a minute walk from the metro station (same line of the airport) and 10/15 mins walk to the touristic centre and the river.
The flat was sparkling when we arrived, the cleanest house I have ever had in my long experience with Airbnb.
Easy check in, fantastic check out. Yves told us to leave the house at any time we wanted. We asked for late afternoon and he was OK as there weren't reservations for that day.
The house is quiet and the area is safe and well served with bars and restaurants. For breakfast there is a pastry shop/bar called Nandinha and for lunch a churrasqueira both just 1 min walk from the house. Both place offer quality food and they are really cheap.
I am so happy about my stay at Yves's house that I give 5 stars to this accommodation!
