My wife and I spent 3 nights in Sofia's apartment in May 2017. It is very clean, quiet, spacious, and comfortable. It is a 5th floor walk up. That is the only negative. It has very good A/C, and Wi-Fi. The famous Tram 28 stops right across the street, as does bus 709, which goes to the Restauradores Metro Station, a convenient hopping off point for virtually any area of Lisbon.
