Eduardo was extremely patient and helpful with giving me directions from the airport to the city center as I couldn't figure out the metro machines due to a language barrier.
Once I arrived, he walked me through the apartment and showed me how everything worked and even gave me some tips on where to go via message (which was greatly appreciated) and in person.
The location is great... lots of casual bars (El Rey was my favorite!) and nice restaurants in the area and walking distance to numerous sights and the riverfront. As it's so close to so much, it's a great place to stay if you want the option to take a mid-day break without trekking far from the sights. Oh and the mini split AC system was wonderful as I didn't expect Porto to be humid so it was great to turn on some AC while sleeping.
