Mattia was extremely responsive - so much so that I got locked out at 4am and he happily opened the door for me - he does live next door to the apartment so he's around. He also meets you at the check in and gives you all the information you require for your stay.
The Apartment was clean. It's a 10min walk to the centre so location is pretty decent.
Plenty of cafes and shops in a 2min walking vicinity.
