Claudia is a very reliable, professional, warm host who thinks of all the little things that make a stay special and more inviting and comfortable. The flat is in a wonderful location and Claudia provides some history and narrative of her own about the location too.
The only negative was street noise (motorcycles, groups of people talking loudly) transmits easily through windows to bedroom which faces via dei Funari a small street. This may not be the same every night of the week but we happened to stay on a Saturday night and there was noise till 3am or so.
Still would recommend highly for location, professionalism and hospitality of host Claudia, maybe just bring earplugs if noise bothersome.
