Catarina is a great host. We arrived 2 hours after we were supposed to be there, due to a flight delay, in the middle of the night. Catarina was waiting for us to let us in and show us around quickly before leaving us to sleep. The next day she gave us fantastic tips of the city of Porto, good recommendations and she is very friendly and helpful. The flat is stylish and spacious, and just a few minutes walk from the main shopping street in Porto.
I would recommend this Airbnb to anyone who wants a cool, relaxed stay, where the host really knows how to make a good trip.
