Found the hotel Natucci via excellent reviews on Tripadvisor. I booked it for 5 nights for a group of 23 Australians exploring Tuscany. Everyone found the experience memorable.
The hotel is close to all facilities, at the front desk Vincenzo is very helpful and attends to every request, the rooms are simple but clean and have all facilities. In the kitchen Vincenzo's wife Maria prepares the best of Tuscan dishes.
We had some celebrations during our stay and a suitable cake, champagne etc. were organised with no fuss.
Best of all, the price was extremely competitive. It is unbelievable that the hotel only qualifies for a 1 star rating.

For a hotel with 1 star this hotel offers a great value for money ratio.
Nice breakfast, clean and tidy room, and friendly and service minded staff, who will go out of their way to help out.

Only drawback is that the rooms are sparsely furnished.

As I understood this hotel qualifies for 3 stars if it wasn't for some local tourist organisation politics.

So if you are looking to stay in Montecatini Terme to enjoy the spas, or looking for a well placed base for a trip around Toscana, this is a hotel for you.

Stay at Albergo Natucci when going to Montecatini Terme! This hotel is clean, spacious and beautiful. Vincenzo, Maria, Anita, Guiseppe and Mrs. Ilda are very gracious and wonderful people that truly care about their customers. The food is homemade and delicious. Absolutely the most wonderful experience in Italy!
