In Vila Nova de Gaia with good access to Porto via the Ponte Luis I bridge. The entrance is on a very steep incline. I had inquired about parking, there's absolutely no parking on their street, but they indicated there was parking at the base of the Ponte Luis I bridge. What they didn't tell me was that there's an elevator within the parking that takes you up 8 levels to almost their front entrance. So, without this knowledge, I walked with my suitcase up the equivalent of about a 9 story building! The hotel is apparently "serviced apartments", very Spartan conditions, low, sparse lighting, tiny bathroom with a shower that had no shelf or ledge to even put a bar of soap on, the mattress was sort of a very hard futon pad of some sort. There is an area with a tiny kitchen with some dishes, utensils and appliances. The metro going across the Luis I bridge is just above the hotel and is pretty loud. To cap it off, I was given an envelope that included "everything I'd need to know." I arrived in the early evening and intended to review this after I ate. When I returned, the entrance/office was closed, there is a side gate with a key pad but does not use your key card, it requires a code. The code was in the envelope. I lucked out as another guest arrived just then and followed them through the gate! This seemed like essential info that someone should have mentioned! The Port Cellars are all in Vila Nova de Gaia, otherwise I strongly recommend you stay in Porto.
