This was definitely one of my best airBnB experiences.
Communication with Carlos was simple and quick, he gave me excellent advice on how to travel from the airport, and was very welcoming. The flat is absolutely great, very spacious and well decorated, and I immediately felt at home. Being in the center of Bica is also a great experience, and the tram makes it even more fun and typical. I'd definitely come back to this flat when I'm back in Lisbon.
