This is a great place to stay right in Campo di Fiori. You are right in the action, but the windows are AMAZING, so there is no problem with noise. We stayed 3 nights with 2 kids (5 and 8), and the property was perfect. Excellent location, the apartment is very old but in great shape and clean. Communication with the host was great, she arranged our transportation from the airport and helped us get a taxi to the correct part of the train station on departure. The kitchen is well-stocked and had fruit, wine and water to get us started. Highly recommended.
