We spent 4 nights in Federico's apartment in October. Great proximity to the Travestere neighborhood, and easy to jump on the Tram downtown to the sights. Apartment is very well-equipped and well-stocked (food and drinks in the kitchen, bath toiletries). A map and two free bus tickets were thoughtful extras! Mattress slightly soft for our preference. Wifi was excellent. Great parking right in front of the apartment for our car.
The neighborhood of the apartment is super quiet, but the walls of the apartment are a little thin with an apartment immediately next door. Federico was very easy to reach online and his father and housekeeping staff were very helpful during our stay. Would recommend for a home base in Rome!
