Nothing special, but ok. The photos are overselling the place a little.
There is also some mold in the bathroom.
The AC is nice and works.
Pretty calm except on nights where people party, for example on Sao João, but that is to be expected.
The location is very good, with lots of nice restaurants in the neighborhood.
All in all, you will not regret it, but if I have to be objective, it is 3.5 stars, not 4.
