As the vast majority of guests have commented, Maurizio is an exceptional host, always offering good advice, friendly and attentive. Many hosts don't offer their mobile numbers and prefer to always contact via Airbnb chat, which, although safe, is not proactive, but Maurizio instantly offered to let us chat via mobile, which was great and helpful.
As for the flat, it is very spacious, the beds are comfortable and it is excellently soundproofed - a must, as it is on a busy road. Even the noise of the tram, although not completely, is very muffled. There is a well-stocked supermarket just a few minutes from the flat, as well as restaurants, pharmacies, ice-cream parlours....
All in all, a highly recommendable host and flat. Thank you Maurizio!
