The apartment is everything we wanted for our stay in Lisbon. It was located close to many bars, restaurants, shops, and metro stops but was not busy or overrun by tourist or local traffic.
The building and apartment itself are very safe and we had no issues with street noise or noise from neighbors.
There is a small snack shop/ Market about 200ft from the apartment that can provide beer, wine, bread, juice, eggs, etc for your place at extremely cheap prices. We stopped at least once every day to grab a few things.
Pedro gave us helpful tips about what to do and where to eat around our area of the city and even accommodated a taxi to the airport upon checkout. I highly recommend this place and hope to stay there again in the future!
