We had a very nice experience in Cristina's place, she's also very nice to us. Her place isn't far from the Coliseum or other important places in Rome, you can even reach them by foot or if you want you can take the metro or the bus which is also close to the house.
However, putting aside the fact that there is a restaurant that works until very late which can be very noisy during the night, in general we can say that we had a great experience in Rome thanks to Cristina.
