We loved this apartment, as it was in a perfect location for exploring Porto. It was very clean and equipped with everything we needed to make coffee and breakfast in the morning. Everything was in very good condition and well maintained. The cool modern design was also much appreciated. The young man, Jean, who checked us in was very helpful, recommending a bike rental place and restaurants to visit.
The only thing I would caution other visitors about would be the lack of air conditioning and screens on windows. Our visit was the end of September, so it was not very hot outside. We still needed to have the windows open as it was in the mid-70s, and it was warm in the apartment. Unfortunately, we all got eaten up by mosquitos while we were sleeping since there were no screens. Legs, arms, face, neck--itchy bites everywhere. They did have fans, so we had to make due with them and try to keep the windows closed as much as possible. I know screens are not common in Europe, but I wish they were! So if you plan to bring a baby or child I would also bring a mosquito net with you.
