This is a very nice property.
It is located in a very nice residential section of town. While it is away from the historic central business district, it is easy to access that part of town through frequent bus service and the metro, both of which are easy to use (I speak no Portuguese), safe, and economical. I enjoyed being in a low-key part of town. The apartment is very large, with two very clean bathrooms and a nice, small kitchen. The view is spectacular.
My only suggestion is that it got very hot. Our trip happened to coincide with an atypically hot spell. A couple of fans would have been appreciated. But this is a rather minor issue with what was a very nice stay.
