Daniel was very accommodating. We were late arriving into Porto but we kept in contact and he met us and walked us through the apartment and a map of the city even though it was past 10pm. The apartment itself is big and stocked with everything you need from extra towels, extra bedding, and even toiletries. The apartment is about a 15 min walk to city center and more if you plan to go down by the river front so be prepared to walk but otherwise a great quiet location to get to know Porto in.
