We stayed for 3 nights at Anna's place..the place is very close to the Colosseum (about 750 m - 5-7 mins walking) and about 5-7 mins from Roma Termini station by bus..the apartment was very cosy and comfortable and Anna welcomed us and showed around the house even though we reached late at 9.30 pm..the only problem we faced was in terms of directions from Roma termini station (English can be a problem in Italy at times) and the bus stop suggested by the host was not really right and we could not convey the same to the driver..apart from that the stay was pleasant and we were able to walk to most of the places in Rome from our place!
