We stayed in this hotel with a group of friends on a choir tour. Cheap and cheerful is about the best description - the rooms were €49 B&B and the proprietor was extremely helpful and friendly. Our large room had two twin beds and a pair of bunks, and overlooked the street so was occasionally noisy (mostly our group returning at odd hours, though, so we didn't complain!). The bathroom was small, but functional, and the beds were pretty uncomfortable, but it's clearly geared up for large groups - it's the sort of place school trips might be accommodated.
Breakfast was pretty ordinary, but plentiful enough.
The location is great - Montecatini is certainly a town worth a visit. If you fancy a romantic weekend there, stay somewhere else, but if you're on a budget, especially with children, this hotel would probably fit the bill.
