A host that goes beyond the usual checkins to make sure his guests are happy and he helps out where he can (in our case we did not understand Italian and could not use the information we got on the phone and he took the call, pressed the appropriate numbers and got us all we needed). He is fluent in both English and Italian.
The apartment is cozy with nice comfortable and useful furniture (not the usual cheap Ikea stuff, what Ikea furniture he had was the good stuff). It has lots of light with windows throughout. Nice patio, fun views. Comfortable beds and bedding.
Great experience. We liked his coffee and restaurant recommendations too, very local and good.
I highly recommend this apartment.
