We stayed at Carla's Airbnb for 3 weeks while working in Lisbon. The WIFI worked great with 2 people on video calls often. Like most of the other reviews say, Carla was an amazing host! She met us in person upon arrival and kept constant communication with us. She even brought us dried wood/pinecones when we asked if the fireplace worked :) The location is great! On a hill a short walk from Principe Real and Chiado. We ate at a different restaurant every night, and explored different areas every day. The apartment has a comfortable bed, fireplace that works, well stocked kitchen/bathroom, plenty of space for a couple. Because we were working EST hours, the only drawback was we were not on the same sleep schedule as the neighbors and the stairs are right next to the bed. That was our fault though, sleeping until 11 am every day! Thanks for everything Carla, you made our time in Lisbon amazing!
