Pedro's place is right in the heart of Barrio Alto and perfect walking distance to everything in Lisbon. Check in was smooth and very convenient. The place matches the pictures exactly. I never met Pedro in person but he was very fast to respond to any messages. Overall it's an amazing place.
A few small cons -
1) It was cold in Lisbon when I stayed and the downstairs doesn't get warm from the upstairs AC. The upstairs (bedroom) is fine though. I needed a space heater downstairs and Pedro quickly provided one.
2) There is some sort of water leak coming from the bathroom faucet which left a large puddle on the floor when I checked in. he promptly sent a cleaner to clean it up. However, I think the leak is still there and a towel was simply used to soak it up during the entire duration of my stay.
