We (my husband, son and I) very much enjoyed this apartment. The location was on a very interesting road with galleries, a great burger spot and a children's book store with THE best chocolate cake we had during our holiday in Portugal.
Beds were comfortable, wifi was good, host was very flexible with check in, and they even brought us a fan within hours of asking as it was quite hot. Generally a quiet area with occasional trucks, late night crowds and dogs & bird sounds.
Would highly recommend their place and a visit to Porto!!
