mini casa is a great place to stay in rome. its not in the busy centre but we could reach everything without much effort (walk/metro/bus). very uncomplicated communication and check in, everything was perfectly clean and we felt really comfortable.
only manko was the near location to a busy street (noise), it is not loud when the windows are closed but neither is it quiet.
in general mini casa is absolutely worth the price and i would definitely recommend! (:
