My father and I stayed at Pedro & Irene's place for 2 nights while we explored Porto. Pedro met us when we arrived and was very helpful in getting us oriented to the city - he gave us a city map and provided several recommendations of places to go and things to see during our visit. The apartment is spacious and comfortable. It is just outside the center of town and within walking distance to everywhere. I'd highly recommend it as a place to stay on a visit to Porto!
