We had a wonderful stay in Porto. The apartment was just as described, located close to the city center. The flat is really stylish and had a lovely balcony. The kitchen was well equipped, so we could prepare our own meals.
Luís was extremely friendly and helpful. He gave us insider tips for our stay and also shared an online map with points of interest, must-sees, bars, restaurants, shops etc.
We would really recommend staying in this apartment and would do it ourselves again.
