A wonderful place for a long stay and worth the price. On the 11th floor of a well serviced building with a doorman, fully equipped with absolutely everything you might need in the kitchen or bathroom. Only thing was missing was an indoor drying rack for washed clothes, so that's my only suggestion :) Even though on the map it looks like it's far from the center, there is a metro station for the Yellow line 2 minutes from there, and it's so well connected to the other lines that you can easily get to the center in 10-15 minutes metro ride. The airplanes aren't as frequent or loud as I thought, and its quite fun to watch them take off from the roof of the building.
The supermarket Pingo Doce is also 2 minutes away, and it has everything from cooked meals to fresh pastries. All in all a great stay.
