The appartement is very clean and all the interior is simple and modern. it's on the first floor and therefore doesn't get much natural light. But after roaming the streets of Porto all day, you will be relieved about every flight of stairs you don't have to climb up.
The location ist great, because it's in the city center, walking distance to all the big attractions and neighborhoods, but just far away enough from the beaten path that you don't step into crowds when you leave the front door. It's a little difficult to find at first, because Google Maps gets confused by the small alleyways and there are several gates to the little private street, but you need the key first, which is located at the biggest gate between Orpheu Porto and Starbucks.
The communication with the owner ist very friendly and easy via WhatsApp.
The only negative is that the walls are very thin, so if the neighbors are having an ABBA Party, you are having an ABBA Party.
