We spent 3 nights at the apartment and it was great. It's ideally locate, just 10min from the center, which means it's away from the hustle-bustle of the city, while remaining quite central. The apartment is super clean and quiet. It has all the specified amenities. We did not cook so we did not use the fully equipped kitchen, but if you could leave some kitchen towels there, that would be perfect.
Also, a very special thank you to Pedro, who was there for our check-in with lots of info about the place and Porto. He was also contactable on whatsapp and replied instantly to a question I had, and he was very helpful and kind, just like all the local people we met in Porto. We thoroughly enjoyed our stay and we will be back hopefully!
