The host was very kind and helpful, in the first day he was waiting for us and he welcomed us. In the room there were some informations about the city: map etc. The host answers very fast. The apartment is close to the shop (ca. 1-2 minutes), city center (ca. 5 minutes), public transport (ca. 3-6 minutes). The apartment is nice and clean, rather small (but for one week stay for 2 persons might be ok). I highly recommend it, it is worth this price. It was wonderful stay in Porto for us.
