Monica was very nice and the communication with her was perfect. The apartment is great, large and and a perfect fit if you need three bedrooms and an elevator (we stayed with a toddler, a stroller and a senior person). I stayed in January and the apartment was warm all the time. The unit had everything we needed to cook and clean, so we didn't have to buy anything. The location is very good, since it's at walking distance from the Roman Forum, the Colosseum, bars and restaurants, and just 10 minutes away from Trevi and 10-20 mins to other locations in the downtown.
The apartment does not have a microwave or a dishwasher, in case that matters, but it's not a big deal, I would stay here again.
