Very cool and absolutely more than worth it!
The place is very clean and Luis is a great host with a lot of cool tips for Porto.
In our 17 days Portugal trip, Luis was the greatest host.
A big thing go mention: The beds are way bigger than you might expect from the pictures! We (two) could sleep in there without any issues.
The walk into Porto is not far and very entertaining.
Last but not least there is a big Lidl supermarket like 50 meters away.
