The apartment is very nice, the company offer a office where you can leave your belongings until the check-in time. We had an issue with the key of the apartment, when we arrived the box, where the key supposed to be, was empty, we had to contact the company, and after about 40 minutes they arrived with the key.
Our stay was just for one night, and the shower drain was not working good, so the shower got flooded.
The apartment is about 25 minutes away from the center of Porto, you’ll need to take an Uber or taxi to arrive there.
