Rosa and Antonio are very kind, they received us after midnight and let us leave our luggage for a couple of hours after the check out.
The apartment is nicely located, perfectly clean and artistically furnished.
On the other side, the apartment probably used to be a shop, so it is located directly on the street, which makes it quite dark during the day (need to leave curtains closed to have some privacy) and pretty noisy in the morning.
Overall it was a nice stay, and we would definitely recommend it to people who plan to wake up early and spend most of the day out visiting Porto.
