Pros: the apartment is well decorated and well located in the historic district. You cannot drive to the apartment (even to drop off bags) in the afternoon/evening because it is in a pedestrian zone, and it is a very steep walk with many stairs from the nearest public parking lot to the apartment building, but Giuseppe picked up three of our four bags in his small car and delivered them close to the apartment.
Cons: access to the apartment requires walking up three flights of narrow stairs inside the building. It was very hot when we visited, and the air conditioner in the living room (where one of the two double beds is) could not adequately cool the space. There is no AC at all in the upstairs portion where the second bathroom and the fold-out sofa are located, so they were unusable. There is also no space to fold the sofa out, so we had to remove the mattress and put it on the floor of the living room to make a third bed.
If you are visiting the temples, I recommend staying outside of town and visiting the historic center but not staying there. The center is much less accessible than in other historic hill towns we visited in Italy.
