My wife and I enjoyed the apartment very much. It has a very convenient location - 28 tram, grocery and restaurants are all practically "down stairs" in the square nearby. The apartment itself is very spacious for two people. It is clean, modern and very well supplied (kitchen, bathroom, towels, even dishwasher and laundry detergent). It felt like a home and provided a very comfortable stay for us at a very reasonable price.
Paula is also wonderful host - very responsive, gave us very detailed local tips and a nice bottle of Port to welcome us. I'd chose to stay here again or recommend to my friends visiting Lisbon.
