We had an amazing stay at Maurizio and Cristina's apartment. The flat was clean, tidy, modern and comfortable. The location was really good - we walked to all of the sights (5 mins to Colosseum, 20 to Trevi or Pantheon).
Cristina was easily contactable, and was forgiving when our flight was delayed. She made us welcome, and gave us tips on where to go.
We had the best time in Rome, with the best views, food, and drink. Would definitely recommend Divin Ostilia, a small wine bar/restaurant just a couple of minutes from the flat. Grazie!
