Fantastic place! I would recommend this particularly for young groups visiting Lisbon. The flat is on a fourth flour in Barrio Alto, an area known for its nightlife. It can get a bit tiring going up the stairs after a long day, and nights can get noisy with the crowd outside. But other than that, the place is perfectly clean, very well equipped, and Joao is a star. He recommended really good places nearby and was very helpful when needed. Would definitely recommend.
