We stayed here for two nights and aside from the steep stairs and smelly stairway (as mentioned by a previous reviewer), we found our stay here to be excellent. It was a last-minute booking after changing our travel dates and from the date of booking, received a text from the property. They were in touch again closer to the trip and then during, and were more than accommodating. Our flight to Madrid was at 4pm and they allowed us a generous check out time so we could enjoy Porto longer without feeling rushed. The building does have a code to get in and then you have a code to get in your unit, which makes it easier than waiting for someone to meet you with a key. The code for the unit does get updated with each guest. We were on the first floor, which still required going up a narrow, steep set of stairs. As much as we didn't care for that, it didn't take away from our great stay. The room was clean and came with everything we needed. The views from the kitchen and bathroom were amazing, even if the weather didn't cooperate. Overall, we were happy with our brief stay and would gladly stay here again, but only on that first floor. It's in an excellent location right that's easily walkable to restaurants, bars, cellars, shopping and more.
