I found everything as described. I had to separate the time of my stay between work and travel, and felt that the loft was spacious and comfortable enough to do this (and no problems with the wifi).
Although the apartment is not located within the historic center, it is within walking distance to it and to the train station (10-15min). There is also a good supermarket across the street, as well as several restaurants nearby.
Fabrizio was very helpful and made a lot of (good) recommendations.
