Comfy at the Coliseum is an excellent choice for a large group visiting Rome. It has a great location, with short walks to the Coliseum itself and to the metro station, taxi stand, tour bus sales and pickup locations, good coffee bars and small shops.
The four bathrooms and showers are very handy (no waiting!); water pressure is excellent and the towels provided are very good quality. We visited in July and a good refreshing shower is welcome after a long day sightseeing and shopping!
