We had a very nice stay in Porto! The apartment has the perfect location for when you want to stay in the historical center of the city. You're very close to the Douro river which is nice. Paula & Rafael were always available and eager to help.
The only thing that was missing was an airconditioning. It gets very hot in Porto, so you have to be able to get along with warm temperatures in the apartment.
But overall we really recommend the place!
