The apartment was just what we were looking for: fully equipped, and at walking distance to the main touristic spots (although in a very calm street at the same time).
Sofia was just the perfect host. She welcomed us at her apartment and gave us lots of useful information. She was always very reachable and the communication was really fluent, being also flexible regarding the checkout time.
All in all, I can only recommend her apartment for a stay in Porto. Thanks a lot for everything, Sofia!
