This apartment was fantastic. It's a great three story apartment right in the heart of the city, situated on a private courtyard with its own private patio. The hosts were also friendly and helped arrange luggage drop off for us when we took a side trip.
The only issue is that the air conditioning did not work as advertised during our entire stay, so we were completely unable to use the top floor bedroom and only used the upstairs apartment to sleep - even then, it was not cool enough to sleep at all comfortably. We were told it would be fixed, but the spare parts never came in. We asked the host for an electric fan and portable A/C, but neither worked very well ... and we had to come home every few hours to dump out the water dripping from the portable A/C. We asked to talk about a discount because of all this, but were told it was not possible.
We did love the apartment and if the A/C had been functional or repaired, this place would have been perfect. But we selected the apartment in part because of the promise of A/C (August in Rome...) and we're disappointed to have paid for a three bedroom apartment when our family of five was mostly limited to one of those rooms for the whole week.
