Ours was a very last minute plan and Gabriele accommodated us excellently for the circumstances.
He came to receive us directly at the Waterbus station, after giving us directions to get there. He personally explained the rules of the house and has a little booklet that guides you on house amenities and local attractions. He is quite reachable if you need anything.
The apartment is located in a quiet area but is close to most attractions. Everything is within a 10 min walk.
