Guglielmos place is fantastic - one of our favorite AirBnB experiences we have had anywhere.
It was the perfect size for two and had some of the best amenities of anywhere we've stayed. Kitchen was great and well stocked, laundry was great, bed was comfortable and most of all the terrace / view are ridiculously good. Close enough to downtown to walk in a reasonably short time (took us 15 min or so), nicely separated from the hectic center part of old town.
Guglielmo was also a very thoughtful and helpful host making sure we knew all the features/usage of the space and had good info about area amenities etc. We loved our stay and would definitely stay again.
