Let us be clear about this: we absolutely loved our stay in this apartment! it's relatively close to the city, still pretty well reachable by car, the air-conditioning work well and the roof terrace is absolutely amazing.
However, there are two things we disliked: the bathroom and parking our car.
The bathroom is very small and it's only separated from the bedroom by a glass door, which barely blocks any sound - so be prepared to hear more than you want to hear when your partner needs to go to the toilet at night.
Regarding the parking problem: there is a parking garage in Via Benozzo Gozzoli. However, this is only a deposit for a parking garage in the city center and therefore isn't open all the time. You can call them, and they are always willing to help (they also speak English pretty well), but sometimes they just can't help you. The first day we've paid 30 euros for 24 hours, but we found parking was a bit stressful, so we didn't make any Roadtrips any more and simply left the car there for 3 days and managed to get a special price (54 euros). Unfortunately for you we don't really know why we got the discount, but it might be worth a try to negotiate.
Again, we'd like to stress that we've truly enjoyed our stay here - we can recommend it.
