This is an amazing location with amazing hosts. After our arriving flight was delayed, one of the hosts changed her schedule so she could still personally meet us at the apartment. Throughout our stay, communication was very easy, thoughtful, and thorough. Every question we had was quickly answered.
The apartment is right in the middle of Porto, with easy walking access to all the major sights. Right now there is some construction on the street as a new metro line is being installed, but eventually this will make the location even easier to access from the airport or other locations outside the city center.
We loved our stay and would highly recommend!
