Cristina was a very nice host (!we only spoke Italian with her!), offered to pick us up and drop us off at the airport (for a reasonable fee), even offered us pizza as we were arriving late! She also drove us a bit around the area and explained where do we have to get the metro next morning, where is good coffee, restaurant, supermarket, etc. The location of the apartment is convenient, connected by various types of public transport and walking distance from some sites (Coloseum, etc). The apartment itself has two double beds so it was perfect for the 4 of us, especially since we basically only slept there - might be bit tight for a longer stay. The bathroom was very basic but overall ok.
