My friend and I were very comfortable in Ilaria's "Nina's House". The apartment is in a fantastic location - a little wandering brought us to a restaurant that we loved and went to three nights in a row (Ai Tre Scalini, and it has late hours), and the Colosseum is less than a 10 minute walk away! The neighborhood felt completely safe, even walking to the Colosseum at 1am on our first night. Ilaria was easy to communicate with and very nice and the apartment was great to come back to after a hot Roman day. Highly recommended!
