As a host, Miguel was really easy going letting us leave the luggage before the official check in and was very helpful with various tips about the city. The apartment is located in the very city centre close to both historical sights and the night life, so don't expect silence on the streets. The place is really tidy and nice - I would especially highlight very good and comfy beds.
Recommendable for everyone who doesn't mind the cheerful and loud daily rhythm of the people of Porto! :)
