Stayed 5 nights at Casa Calpurnia, Claudia was very helpful and the checkin and checkout was smooth, she even arranged a taxi for us to the airport on our last day.

The apartment is very nicely decorated and has all the conveniences you might need (apart from a washing machine and dryer) to make your stay comfortable. The airconditioning was most welcome given that everyday was around 35 degrees celsius during our stay.

The location of the apartment is perfect. You can literally see the Colosseum when you walk out of the front door of the apartment complex. There are plenty of things within walking distance, and the bus and metro aren't far away at all. There's a handy water fountain across the street that you can use to fill up your water bottles (don't bother buying water in Rome, you can get fresh, cold spring water for free out of the myriad of water fountains all over the city).

The only negative aspect of the apartment was that it was quite damp, towels literally never dried, and as we were forced to hand-wash our clothes during the first few days of our stay, it was hard to get them to dry as well. For the benefit of future guests, there is a laundromat at Via Cavour, 168 (20mins walk from the apartment) that will do a wash and dry load for 8 euro, we found this towards the end of our stay.
