We stayed at José's house for two nights and it was absolutely amazing! The house was exactly as it looks on the pictures, the views are even better than we expected and sitting there on the balcony while drinking coffee and looking over Porto was so lovely. The walk to Porto is not the shortest but it's by the river and the views are great. Getting to the house is probably easiest by car as the streets are pretty steep like everywhere in Porto.
José is also the most lovely, the communication was easy, he met us when we arrived and showed us the house and it was so easy to contact him during our stay. Would definitely recommend staying at this house!
