The house is perfectly located. Tomás was very nice and helpful. The house is clean and decorated with good taste. It has a small kitchenette where basic cooking can be done and the couch-turned-bed was confortable. Although it personally didn't bother me very much, the main street can be noisy on friday and saturday nights, because the area is quite popular for going out.
Overall, it was a very good stay and i would definitely consider it if going back to Porto.
