We stayed in Joao's flat this january for a few days. It was really wonderful time! The location is perfect: this is calm area, but very close to all landmarks.
We didn't met Joao (that's pity), but his mother and brother were waiting for us with bottle of wine. They provided all information we needed about the city, activities etc.
The flat is cosy, nice decorated and you can find there everything you need. There is a big terrace with a fantastic view.
So, it's highly recommended!
