We had a good stay at Paulo's for a quick weekend getaway to Lisbon. The area is good - Plenty of places to eat/drink, scooters near by, public transportation (including a train station) near by, about 15-20 min drive to airport. Lots of stairs to get to place, but that is expected in Lisbon.
The place itself is quaint. The stairs to get to the apartment were a little rickety but nothing dangerous. If you have lots of luggage it may be a small challenge, but nothing crazy. The restroom is small. Wifi wasn't that great. Its not a dedicated line, but a cellular hot spot. It worked well one evening but was really slow the rest of the time.
Paulo communicated well and checked in with us regularly. Good place for a quick stay.
