If you're looking to visit Porto then this is the perfect place to stay.
It's right in the middle of the city, with most popular attractions under 10 minutes walk away. Plus you're made to feel really welcome right away with tips on where to visit, eat or drink, we couldn't check-in until gone 10pm but it wasn't a problem and our hosts still made the time to welcome us and make sure we had the full welcome.
It's also extremely clean and tidy, has everything you need to cook for yourself if you want to, and was a very nice temperature (even when it was 30 degrees outside!)
All in all can't recommend enough and would certain visit again myself.
