Sofia was very friendly and shared lots of tips about the city, and available for questions anytime. The apartment was in a perfect location, close to Rossio metro and trains (easy to get to the airport, Belem, Sintra, etc), with lots of food options within a few minutes walking. Lisbon is very hilly, so expect to walk up some stairs to get there, but it's normal for the city. The apartment itself is cozy and quiet, and equipped with everything we needed. Bathroom might be small if you are a large person, and you can't take two consecutive long hot showers in a row (the hot water will run out), but that wasn't a big deal for us. I'd definitely recommend this place and would stay there again next time!
