This was fun place in a great location. We were no more than a few minutes walk from all of the great food and tourist locations you could want. Marco and Claudia were great with communication. When we had questions they were very quick to respond.
If you aren't familiar with Rome and its public transport, I'd recommend taking them up on the transfer from the airport via private car. It will definitely save you time/frustration. The other option really is taking the Leonardo Express to Roma Termini, and then getting a cab or bus. When all is said and done, you may save 10 euro but it can be a little frustrating.
The apartment is charming and the facilities are good. Claudia and Marco even stocked the kitchen with some fresh fruit and other little items. The bathroom and shower situation was a little bit underwhelming and could use a bit of an update, but it did not take away from our stay. The portable AC unit in the bedroom area was a life saver during a hot July in Rome. The apartment is on the fourth floor of the building, so keep that in mind. Marco was very nice and helped bring our bags up. I would definitely recommend staying here.
