We loved the Monti apartment. It is in a beautiful old building and perfectly situated--a few minutes walk to the Colosseum and the historical center, but on a quiet street with lots of great restaurants, a lively piazza, and a metro stop close by. Barbara was a great, helpful host and very charming even though we showed up early! We'd stay here again in a minute. Highly recommend La Taverna dei Fori Imperali nearby.
