This flat was absolutely perfect for our stay in Porto/Vila Nova de Gaia. The air conditioning in the Master Bedroom and in the living area (kitchen, dining room and living room) were key during the hot weather we had when we stayed and worked very well. (Note that the other two bedrooms do not have air conditioning, but that didn’t impact us since we are a couple and chose this flat for its location more than anything).
The proximity to the Dom Louis I Bridge and the Port cellars and other activity along the bank of the Duoro River was great. Everything was walkable, including the great restaurants in Porto across the river. The view from the little balcony out over the Duoro is even more stunning than the picture accompanying the listing suggests. Our bed was very comfortable, the shower was great (though we seemed to not have hot water on some mornings), and the living area cozy.
Pedro was very responsive, met us as soon as we arrived to check-in (despite arriving a few hours later than originally planned), and gave us a tour of the apartment. The apartment was extremely clean and modern. The kitchen was fully stocked with dishware and cookware as well as an espresso maker with pods for us to use. The bathrooms had spa-like touches and feel to them. The apartment is in Gaia, across the river from Porto but on the same side of the river as the port wine cellars.
Overall, this was an outstanding stay and the accommodations were more than adequate and very comfortable.
