Josefa's apartment is perfect for visiting Porto. It's ideally located - right in the core on a quiet plaza. The apartment itself was extremely clean, had all the amenities we could picture using, and it was very modern and cute.
Josefa herself was extremely helpful - she gave us great recommendations - food, places to see etc... and was easy to get in contact with. All in all, we had 0 complaints, and our trip to Porto was made better by having such a nice place to stay at.
