We had a lovely stay at Pedro and Claudia’s apartment. Communication with Carlos was very easy and he was pleased to help us with any questions we had. The stairs are steep but if you’re in normal condition you should be just fine, it’s part of the charm of Lisbon! The apartment has all of the basics equipped, it gets a little hot during the summer but we slept just fine with a fan.
Lisbon is a magical place and if you really want to discover the city I can recommend this apartment!
