We lived one month in the apartment and really enjoyed our stay. We were three people, the apartement is a bit tiny but comfortable and has everything you may need for a few weeks stay. Graça is a lovely neighborhood so the location is perfect (many restaurants, little grocery shops,...), there's a 10 minutes walk to get to Sta Apolonia station (metro and train) and there are also several bus stops nearby, which is quite convenient.
The staff is really nice and reacted very quickly when we asked for items that were missing in the kitchen.
