Giorgia was a very nice and helpful host, I recommend that you take the offer for her to organise a taxi pick up from the airport. At a cost of 50-55 euro's for two of us it was a comfortable and quick way to get to the apartment.
The apartment was as seen on the internet, lovely and tastefully decorated, with big bedrooms and 2 bathrooms. Set in a nice location and in walkable distance to St Peters Basilica, the Colleseum and other attractions were easily reachable by taxi and didn't cost a lot. I'd recommend that you take a taxi with a meter or check the price before you get in a taxi - we were caught out once and paid a hefty price for our mistake.
One thing I do think is important to mention is that the address of the apartment was incorrect and the telephone number for Giorgia is also wrong - make sure that you confirm via email with Giorgia the number of the apartment 120 and not 12 as listed on the internet and that you have her correct mobile number. It got a little hairy when my friend who was already in Rome, couldn't find the apartment, thankfully my taxi driver knew where we were going and was able to confirm the correct number of the house, but also not being able to get hold of Giorgia because of the wrong telephone number had us all sweating a little. It all turned out OK, we made it to the apartment and Giorgia was there to meet us and it really is a very nice apartment so it was easy to forgive this initial misunderstanding.
