Antonio is a fantastic host. Staying at his studio was as if, I had all of the services of a 4 star hotel but with the unique style and local feel as if I were in my own home. He was very communicative before and during our trip - and he gave great local tips for restaurants, live music and art exhibits. The location is pretty sweet too, as you are within comfortable walking distance to everything. No complaints, and I recommend anyone traveling to Porto, to stay at his place.
