It is a great apartment and the terrace is the icing on the cake! Well worth the walk up the steps to the third floor!! It is absolutely in the heart of Porto and you can walk to everything.
Anne was very easy to communicate with and replied promptly to any queries. Unfortunately we didn't get to meet her, as she was away at the time, but her friend, Miguel, who met us and showed us to the apartment was lovely and gave us heaps of tips about where to go, best places to eat etc. Would absolutely recommend the apartment and Anne. She is a great host.
