Perfect location for a charming apartment. Everything looks as in the pictures, it is very clean and the bed very comfortable. However, as other guests pointed out, the internet connection is not stable. In the two days we stayed there it was impossible to (just) check email. Antonella contacted the company as soon as we could let her know about this issue. The service improved but still not enough to avoid having to go to a nearby coffee place to get some work done. It complicated our stay since we were in a business trip.
Another thing that was totally unexpected was the need to pay to Antonella (at check in time) 2 euros per night and per guest. I know about this requirement in many touristic cities as it is usually well stated at booking time in all (very well known) websites for hotels reservations. This information is not stated at the Airbnb site. I wasn't aware that I would have to pay 8 euros (2 guest stayed 2 nights) few minutes after getting into the apartment. I would have been nice to have such information in advance so I'd have had the cash ready in my pocket. It would have avoided an awkward situation that was saved by my friend (to whom I had invited) who luckily had the exact cash.
