Diogo is a great host: responds quickly, showed up even at a very late time of arrival and had a nice, clean, quit and fully equiped appartment to offer! The appartment is located in the city center, close to the main metro station and big city square, right in the middle of the nightlife district, on the other side of the street is a nice bar and the street is full of very good restaurants. Still, the room is very quit at night!
So a very good spot for people that want to explore Porto in a few days. Recommended!
