Very happy with Katia's place.
First the obvious, great location in a secure residential building steps from the Duomo.
We were met by a very nice young lady to let us in, show us the details of apartment and make sure all was well. Setting up and the actual meeting went VERY smoothly.

It's obviously a rental apartment, the usual Ikea stuff and well worn details, but nothing really 'wrong' with the apartment beyond 1 thing, the shower was SO small, I literally couldn't bend down to get the soap. I've never been in such a small shower!?! But, it had hot water, we managed and the bathroom otherwise was fairly roomy and relatively clean.

Overall great great place for the price. As long as you don't expect charming decor or high end fixtures, you will be very happy.
