This is an amazing place to stay while in Porto! The location is great, some 10-15 min walk from the very center, and the place itself is just magical. The hosts are extremely nice and forthcoming, such a nice family, very positive always and willing to help. Huge thanks for having us! Internet is also very strong, although the fastest is in the office at the ground floor so if you need it for meetings or something like that make sure to asks the hosts.
I strongly recommend this place, and if staying again in Porto I would definitely try to stay here again.
