Pedro and Claudia's place was very well located -- a short walk from the main square. It's a little steep to walk up but perfect for burning off all the calories from the pasteis de natas you'll be eating. (Ubers are super cheap in Lisbon so if you have lots of luggage then it would be worth the ~10 euros from the airport to here.) There's steep stairs from the hallway, but that's just the architectural style of this building since it's really old. But the Airbnb itself is very modern. The light structures are a bit low so you might hit them while in the bathroom/living room. Pedro's father, Carlos, was the one who checked us in and our main point of contact for our short stay. He was really nice and welcoming, and communication was almost instant if we ever needed anything/had questions. Would definitely stay here again.
