Nicoletta was super-responsive and helpful. She went above and beyond helping me try to figure out the bus system and some of the apps since my Italian is not good. I didn't meet her in person but she always answered very quickly and sent her father to take care of things.
The apt is clean and comfy, well-appointed and quiet, and easy-walking to all downtown and touristy places.
My only complaint was the hot water heater, which was acting up and needed servicing several times. The heating was affected (luckily there is a wall heater/AC unit that could be used when the radiators were not working) and the hot water for showering and dishwashing was finicky. I had a couple of showers that involved hopping out with soapy hair and having to reset the boiler before I could finish. She said it has never happened before and that she'd be replacing the unit, so I suspect that will be done as the apt is clearly well-cared for and maintained.
Would definitely recommend!
