We stayed there in Feb 2017. The place is very near to restaurants and squares. Vatican city, collossium all are reachable by bus. Bus stand is about 2 3 minutes from the house. Fabio told us it is walkable also, however we didn't try that as we were tired and so did not take a chance.
The place is at conveniently located. The flat is at 2nd floor, The premise is a bit dated. It's a studio apartment. Good bed, sofa, medium size cupboard, bed side racks, and a tiny table with 2 chairs are there. There is a tiny kitchen as well which is inside an almirah. A small fridge is also present there. The bathroom is very small as well. Everything is clean and organized.
Fabio was courteous. He allowed us early check in and had put snacks, yogurt, cakes for us which was very helpful to satiate our need of food when we arrived. We immediately made use of some of the stuff. He had kept tea and coffee as well so we didn't have to buy the stuff. If you are cooking, the kitchen has a stock of olive oil, balsamic and wine vinegar for you. This is also very helpful as usually on these short stays you end up buying and not using stuffs entirely, so you can just use as much as you want without bothering that the rest part of it will be wasted.
There is a small super store nearby. As far as I remember the name of the store is Carefour Express. You will get all food items here. They sell cooked food also but we didn't try it. The price is reasonable and staff is very nice.
There is a restaurant nearby. We forgot to take down their name bit they are on Trip Advisor. Nice and friendly stuuf, super value food and drink. You must try this. The place is about 5 minutes once you come out of Fabio's home and walk towards left.
We tried our best to clean the flat before we left, cleaning all the utensils and making the bed proper. That is almost about it.
Fabio allowed us an early check in and we were delighted by his friendly gesture of keeping the fridge stocked.
Pros -
Excellent location, clean home, polite and courteous host, all amenities present
Cons
Tiny bathroom and very tiny kitchen. Using the kitchen is really a challenge. The premise is a bit dated, the flat is at 2nd floor so if you are travelling with luggage you may have some trouble accessing it. Dated towels.
