Host:
Lavinia is very kind and sweet, communication is very easy (also with WhatsApp) and she is trying very hard to make everything perfect for you.
Apartment:
The apartment was very clean and it's very nice, one bedroom and a pullout couch in the living room. The only downsides are that you have to walk 4 floors up without elevator (but that's the price you're paying to have the nice view from the roof top terrace :-P) and that the apartment is smaller than it appears in the pictures (terrace, bathroom, bedroom). Also there were no sunbeds on the terrace to lie on like in the pictures... which I missed a bit, but oh well. Other than that everything is exactly like in the pictures: Cute and clean little apartment, beautiful terrace with a very nice view around the neighbourhood.
The apartment has everything you need, the kitchen is small but has the most necessary things unless you wanna cook a 6-course-menue... than you will probably run out of pans & pots ;-)
All in all I think the apartment it's good for 2 people, if you're more than two, it is quite small.
Location:
Location is good: A small supermarket (Todi) is located 1min by walk and it has everything you need and isn't expensive. One restaurant downstairs, other restaurants really close. My sport facility was just 2min by car, so it was perfect for me, if you need to get to a metro station (San Paolo) is about 2km away and quite a walk, by car 8min. From San Paolo Metro it's easy to get anywhere in the city quickly, 15min to Colosseo for example.
Neighbourhood:
Very quiet little neighbourhood, in the evening on the terrace very nice to sit and relax. Parking is for free on the right and left of the street, were able to find a parking spot easily close to our front door everyday, which is definitely not usual for Rome.
All in all we really liked our stay there, the apartment is small but superclean and cozy and for two people who love to relax on the terrace in the evenings - perfect!
