We visit Porto for 4 Days and had an amazing time! The apartment is absolutely beautiful, and the view is worth booking it! It's not located in the city center but just a bit outside which you should consider as you have to walk about 15 to 20 minutes to get into Porto centre. We really didn't mind walking every day as the route has amazing views and the apartment is located near all the port cellars. The contact with Mariana was very easy and we had a booking confirmation within 24 hours. Mariana arranged a pick up from the airport to the apartment and also this was really good organized. It is truly a perfect place to stay during your Porto visit.
