This is a AirBnB purpose built Ikea style compact studio in the authentic Porto style old town. They are several little apartments with an office downstairs. I never met Mario, just chatted online, he is easy to reach. The receptionist lives a few blocks away and gave very useful tips. The flat is small but well thought out, everything is included - hangers, iron, hairdryer, cups, microwave, water etc. The only issue was that the drainage in the shower was blocked.
