We loved the apartment ! We did not meet Simone but Sabrina and Paolo. They were really nice. The apartment is huge, more than what we expected. We were 11 and really had space, which is good when you are to stay for a week.
It was also very clean, since Sabrina would come everyday to clean the rooms and bathrooms. There is a bathroom for each room which is great.
It was only a little noisy at night, since there is a lot of traffic, but nothing extreme. There is a charming balcony.
The Wifi was working very well.
The kitchen is not huge but enough to cook for dinner.
The subway station is right beside the apartment, which is very practical. The station is "Baldo degli Ubaldi", and it is 3-4 stations away from the city center that you want to visit.
We felt really at home here !
