We spent two nights at Filomena & Ana's place and couldn't recommend it more. Firstly the apartment itself is superb - beautifully decorated, comfortable, spacious, secure and just a nice place to spend time in. We wish we had more time to enjoy it! As it was we arrived late on Friday night and departed on Sunday afternoon - Filomena kindly was there when we arrived after midnight to let us in and show us around + give us some good local tips. She also was great at responding to messages, knew where we could go to print our pesky boarding passes, and generously gave us a bit more time to recover after I ran the marathon on Sunday morning. The location is superb, we spent Saturday enjoying some of the city's many great shops and eateries - all reachable by foot - and the metro which takes you straight to/from the airport is just a few mins walk away. Highly recommended :)
