Ivana is so nice and so easy to work with. The place is spacious and super quiet at night and for the Americans, the air conditioning is fantastic! The place is very close to the Mercato Centrale and no more than 15 minutes to the Duomo. Like anywhere in Italy there are stairs but if that's not an issue for you, then it's the place to book. There is a grocery store a block away with all that you need for a short or long stay.
The place has a bathroom with a shower on the main floor and another 1/2 bath upstairs in the loft ( but it's a pretty private loft) which just makes it nice to have 2 bathrooms at your disposal.
