Pedro's place is in a great location, right by Martim Moniz square and the metro. As others have mentioned, it is up 4 flights of stairs (that are often dark). I was there in November, and despite the heating unit being on, it was still pretty chilly in the apartment at night. However, the view from the balcony makes it all worth it. It's clean, pretty spacious, has a kitchen, and the shower worked fine for me. Overall, a great base for exploring Lisbon!
