Both me an my company can highly recommend the apartment of Luca. It is next to Vatican and you can easily reach the inner-city by foot. Moreover, the apartment is near to a metro station.
The apartment itself is clean, big, and pretty. You've got everything you need in there. Especially the bedrooms are sized and the rooms have high ceilings.
The landlord is a very friendly person who could be contacted easily. To sum up I can say that I would definiteley go there again.
