Excellent. Clean, comfortable, airy apartment. There is probably no more central location possible, it's directly on the square. There is air conditioning, which we didn't need, but could be useful at times.
Sabina was over-the-top helpful, answered texts promptly, left us with a local cell phone, two beers, coffee, laptop with printer, wifi, some cooking items such as olive oil. Because there were no guests before or after our stay, she allowed us to check in early and leave late.
There is a bit of noise from the very active square between about 10 am and 9 pm, which can be heard in the living room but not the bedroom. We are sensitive to noise but this never disturbed us.
