My friend and I stayed at Between 2 Parks last week. It's simply lovely. Long before we arrived, David corresponded regularly to provide suggestions for places to check out in the neighbourhood, things to do, and insider tips for getting around Rome. He even booked a car service to pick me up at the airport. The apartment is cute and comfortable, in a courtyard in a not very touristy part of town (but still quite easy to get to everything). Check in and check out were very easy. I highly recommend staying here, especially if you need two bedrooms.
