If you are searching for a host that is clean and friendly, than you are on the right way with Antonio. His loft has everything you need. It's clean, cosy and in the Center of Porto. So you don't need a car to explore the city. Everything is reachable by foot.
On our arriving, Antonio warmly welcomed us with a big smile. He also prepared a light dinner for us, becayse we arrived really late. Moreover he gave us very good recommendations about attractions and restaurants. I can definitely recommend Antonio's loft.
