Communication was smooth and self-check-in as well, room was exactly as described in an old town house turned self-serviced airbnb. Private bathroom is a plus in this space shared with lots of other guests, bed was very comfortable and good towels and sheets. Shower only gets warm at most when not the first to shower in the morning. The room doesn't exactly have a window but opens to a small corridor with windows so there is an option to ventilate, the door towards the corridor and shared kitchen could use a lock but still felt safe. The front door was left open most of the time due to the number of guests coming in and out so it's best to make sure you lock your room and stuff. Location is great to explore Porto, many good food and coffee options as well as amenities around, walking distance to train station and metro right in front. Would surely recommend for a city stay.
