Good if you plan on spending your time in Rome outside exploring and only need a place to sleep. Host's communications and transport/directions instructions were excellent.
Overall, this apartment is in a great location. It's extremely small and not particularly comfortable to relax in. It smells damp and is very old - needs some work. Miniature kitchen and shower with 5 mins of hot water makes for accommodation suitable for a busy trip sight seeing - not one where you have a base to relax, cook/eat and recharge in. Bed was comfortable, ladder up to the loft would be difficult for an older person.
