Ana's place is a true gem - highly recommend staying there for your visit to Porto! The apartment is as beautiful, if not more so, as it looks on the photos, and the location is priceless. It is super close to the main historical sites as well as the main shopping area. At the same time, it is on a quiet street with a great breakfast/brunch place around the corner and food shops nearby. We were able to find street parking right on the street (and there are several reasonably price parking garages nearby), and were very happy to have an elevator in the building given our luggage.
Ana is a fantastic host and resource and not just for Porto, which she knows extremely, but for Lisbon and travel in Portugal in general. She is also extremely responsive, thoughtful, and thorough. We were greeted with local pastries, port and coffee, and Ana keeps local guides and maps in several language for the use of her guests. We had a lovely stay and found ourselves wishing we had a few more days in Porto to enjoy this great apartment.
