We had a great 2 nights stay in Porto with Dima. The space was very clean and Had everything we needed (towel, body washes and other items. It is very centrally located and easy to get to main attractions since Porto is such a walkable city. Dima was very accomodating and let us drop our bags off before check in since we arrived early.
The space is a room in his apartment with a attached bathroom which I think we had to ourselves but was not too sure if there were other guests staying there as well since we were out during most of the days we were there. Overall great stay and affordable.
