Ana and Hugo are very friendly and helpful people. Hugo gave me good advice on what to see and do in and around Lisbon.
My wallet was stolen the first day I was in Lisbon, and Ana was kind enough to give me a sandwich lunch for the next day and help with phone calls. They had a couple as house guests who were amazingly helpful and even lent me money!
The apartment is cozy and clean and located in a very convenient area of Lisbon, right across the street from the train station, buses and trams. It is in the middle of nightlife and walking distance from several sightseeing localities such as Baixa-Chiado and Rossio, the Arch, etc.
The apartment is, however on the 4th floor so heavy luggage and inability to climb stairs could pose a problem.
