Cristina is a lovely person, happy to help you! The flat was as discribed, rather comfortable for 3 person as the pull out bed in the living room-kitchenette area is small for two person. It is quite funny as the second bed is not on the same level as the one above is more to say a second bed "on the ground floor". Otherwise the flat is clean as has all the equipements needed.
The bus number 170 leaves just outside the flat, takes ca. 20 min to get to the city/Termini Station. If someone is a bit fussy of travelling in a crowded bus that in 10 min walk you get to the Trastevere Station and can travel by train to the city, 2 stops to get to St. Pietro Station close to Vatikan.
Close to the flat there is a really good supermarket called Simply Market (open 8-20). You can buy everything in a reasonable price. We also find a good restaurant called 158 just around the corner.
Finally if you are looking for a flat not in the busy city for a good price then Cristina is the right choice. :-)
