We highly recommend Casa Marchese.
This beautiful apartment looks like it was designed by a professional decorator. The rooms are large, there is plentiful closet space for storage, the shower is big (didn't use the tub, but it is good sized too).
The kitchen has everything needed plus many extra touches like filtered water filled in glass bottles chilling in fridge, juices, jellies, nutella, muffins, etc.
The Wifi worked well.
And very importantly, we had a wonderful welcome from Rosella's daughter, Caterina. She have us great advice on some local questions we had and provided helpful website links. She even booked a taxi for us when we were leaving... because of the language barrier I wasn't able to accomplish that.
This Airbnb experience made is feel comfortable and right at home...wish we could've stayed longer!
