Ambra's place is conveniently located a couple of blocks from the Tiburtina train station, so we had an easy time using Rome's Metro, which covers all the tourist attractions.
Ambra is great host. She kept in communication with me before our trip, arranged everything, and met us personally even though we arrived late. She walked through the place, gave us a map and pointers, and even helped us store our luggage after we checked out.
Ambra's apartment is very nice inside and out. Basically everything was provided. We arrived too late for dinner at restaurants, and we were able to buy food from a supermarket across the street.
We had a great time in Rome, thanks to Ambra's place.
