we had a great stay at Luca's appartement. Luca very supportive with all kinds of tips to make your stay in Rome as pleasant as possible. His English is very well.
from the appartement it is only a 15 min walk to the Colosseum, and also the metro is very nearby which takes very fast to the Vatican.
Treinstation Termini is less than a 15 min walk and there are busses on the side of the station that take you to both airports for a very fair price.
We had a great time in Rome hope to return one day
