Great location!!! All in all the flat is not brand-new, however everything that you need is there. We asked for an extra set of towels during our stay, which was forgotten at first, but as soon as I contacted the team, a very friendly team member came around and brought the towels, which was really nice. He also gave us extra tips on what to do in Porto - therefore the service in our eyes was great! Thanks for that! Also the communication was great, really quick response times.
One note on the noise: If you're not staying on the top floor, you can really hear every step of the guests above you. I assume that is simply due to the building, so just be aware if that. Other than that the building was quiet.
All in all a good choice for a stay in Porto.
Thanks for a lovely time!
