William is a great host, who cares about his guests, answers very fast and helps out whenever he can. The appartment is wonderful. It is perfectly located and close to all the important sightseeing spaces. The appartment has everything you need and there is also a supermarket and a restaurant (Italian Deli) for best breakfast ever 1min away just around the corner. I was there with my family (5 adults) and would warmly recommend it to everyone else.
