Location is fantastic - walking distance to all the sights in Rome. Room is old (isn't everything in Rome!?) but clean and large enough for two adults. Bed is comfy and linen appeared to be clean. Washing machine was a bonus for us after travelling for a few weeks.
The only negative is that the shower is tiny and does not drain well so be prepared for short showers. The room is in a noisy area so if you are a light sleeper bring ear buds. Would we use this apartment again - yes.
