Lisa is a fantastic host. Check in was very easy and she was quick to respond to our messages. She met us at the flat and gave us some fanastic tips on what to do in Porto.
The flat itself was exactly as described, a very good size for the two of us and within easy walking distance of the main sites of Porto (with good transport links if you don't fancy the hills). Also, the view is even better than it looks in the pictures. We'd definitely stay again.
