Carlotta's flat was just as described and more (just be careful you don't ask taxi for piazza maggaiore instead of Malpighi as we did, it's close but took us longer to reach flat than planned). It was really sweet and cozy place with everything we needed and so many extra touches (juice in fridge, bottle of wine, pastries for breakfast, soap so we could do a quick load of laundry, umbrellas when it rained). As well there was tea and espresso there for our use and a fully functioning kitchen. We didn't cook but was nice to heat up cold pizza, or bring takeaway home. Our first night the beam in the bed broke, we let Carlotta know in morning and she was there within 5 minutes working on a solution. We would have been happy to throw mattress on floor but she had it fixed by that night and was overly generous in compensating us for the hassle, which we didn't feel it was. Was great location for walking around city and all of Carlotta's restaurant recommendations were amazing (unlike hotel recommendations which we have found to be terrible). It was our first air b'n b stay so not sure if it's the norm for a place to be so great but we loved it.
