A quick disclaimer for those of you from the USA.
Please lower your expectations about amenities and conveniences in Italy (and in most of Europe).
Very few places will have a precision thermostat that will allow you to keep a constant temperature, for example. I could go on and one, but, hey, if you are venturing outside of the five-eyes community, prepare yourself for a slightly different experience.
One of the highlights of Roberto's place for me is the mattress. The bed in the bedroom is a bit short, but is very comfortable and the mattress is the best that I've experienced in Italy!
The kitchen is small by USA standards, but it has everything you may need and is very functional. Ask Roberto, if something is not there, and I'm sure they will be happy to provide whatever it is you need.
It is a quiet neighborhood, yet literally just minutes from everything in downtown or in the historical district. Well, it is downtown.
There are 2 grocery shops nearby. I suggest you forget about the smaller one. The larger one is... as you walk out, turn right, right again... 3 minutes later on your left-hand side.
I did NOT like the shower control. It was taking me about 5 minutes to set the temperature. My fiance, who is also much better with joystick, could get the "right" temperature in under 5 seconds.... yeah, from 0 to 90 F in under 5 seconds!
There is a grill and Jacuzzi outside in the yard - we did not make any use of that.
The TV is there and there are many channels, but never got to watch them.... we spent most of the time out.
Unlike some other hosts, these guys are honest and there are hidden fees or charges. Besides of what you will pay on here, you will have to pay the city tourist tax, but that is true about any place in Italy.
