This was a great apartment centrally located near the Duomo. The host gave us a great tour of the working of the apartment (fuses, lights, AC unit) - what he did not tell us was how to open the front door. Unlock it and push the middle button on the door knob. We thought pushing the middle button on the door knob would lock it, nope the opposite, it opens the door.
Also, as other stated, the toilet broke. The top tank was bone dry empty and when we pushed the button to flush the button fell into the tank. We used the pot from the kitchen to add water to the tank to flush the toilet. Ask them how to fix the toilet, so you are not peeing in the bidet or using a pot to fill up the tank. They did fix the toilet within 24 hours and it gave us a GOOD laugh.
The neighbor was NOT happy with us laughing at 10pm and was banging on the wall and on our front door (good thing we didn't know how to open the door right?).
I read other reviews and requested another set of towels for a fee (I think 3 euros). We used the other set of towels for the floor in the bathroom, there is no mat by the shower. So if you don't get an extra towel, you'll be stepping out of the shower wet onto the slick floor and leave a puddle of water.
Overall, I would stay here again.
