Our family of four stayed two nights in Duarte's apartment and really enjoyed the spaciousness and comfort. There are five bedrooms and two bathrooms arranged around a central light well, so there are lots of windows for fresh air (including the ones in front and back of the building. Very bright and open space). Big kitchen/dining space with all the amenities; big living room with a comfortable couch and a ping-pong table! Bathrooms were also large and had excellent showers. Beds had foam mattresses which we found comfortable.
The place was very clean and modern; seemed recently renovated. The location is about a half-hour walk from the city centre, but the metro station is right outside the front door and it was about 10 minutes (or less) by metro (it was an easy half-hour trip to the airport on the metro). There were lots of different ethnic restaurants in the area and a great square with patios and fountains just a few blocks away. (Supermarket right around the corner.) This is a great place to stay for people who like walking around cities exploring different neighbourhoods.
The apartment is on a relatively major street, and the metro station is literally underneath the building (you can hear it rumble past), so if you don't like city noise you might not want to stay here. But we actually found it surprisingly quiet given the location.
If you're looking for space to spread out and you don't want to be in the middle of throngs of tourists, this is the place for you.
