We had a really great time in Cool House Apartment 3. The flat is just as on the photos, very clean and equipped with all the basics you need. The only small downside was the constriction side just next to the balcony, which made us wake up quite early. However, as Porto seems to get a complete makeover, it would have been hard to find an Airbnb without constructions nearby - so it was really the best choice ;)
