We had a lovely 3 night stay in porto at isabels place. We were able to get everywhere we needed on foot including over to the other side of the river for the port wine cellars (a 30min walk). There is a self service laundromat a minutes walk away, and supermarkets nearby. The place itself is clean and stylish, and we found the size very comfortable for two. Communication with Isabel was quick and easy.
Would definitely stay again!
