I had a lovely stay at Guilia and Massimilianos place. It's huge, well lit and full of lovely little decorative and practical touches.
It is easily walkable to everything, ( don't forget at the end of the day you also have to walk up a lot of stairs!) and surrounded by casual restaurants and bars. There's also a great food court next door on the upstairs of the main market.
I kept the shutters of the bedroom open to be woken up by natural light so could hear low level noise from the restaurants in the evening and stall holders setting up the leather market in the morning. It did not disturb me.
Massimiliano was very responsive when I had questions. Plus he allowed me to leave my bag there after check out and pick it up later. When I got back to pick up my bag, he was doing some general maintenance and when I asked why (because the place was perfect) he said that if you did a little often then you avoid any big issues which is an excellent attitude to have. 🙂
