We've been to the Calidario before to swim in the main sorgente pool. Now we booked the New Year four night package and stayed in the residence. The rooms are kept very clean. However as a thermal/spa resort it is very disappointing, expensive and not anywhere near the standards of other therme in Tuscany. First of all we had to pay rent for a "set Cortesia" which is an overused bathrobe and flimsy slippers! Lockers are also on a rent basis and you have to leave a deposit! Room heating is not adequate at all - at times cold. From the room to the resort you have to walk outside, doing so in the bathrobe is uncomfortable as it is cold and using the public change rooms is absurd since you pay a premium to stay in the residence and the public change rooms are small and fill up quickly. Not kept very clean either. If you stay in the Sorgente, there is no eating or drinking (smoking does not seem to bother them though....) but you must get dressed again to go to the bar or picnic area which is outside of the complex. Be sure to have your hand stamped if you are going to the bar otherwise you will not be let in again. Staying in the residence you can enter and exit the sorgente as you please but on a daily basis it is pay as you enter not by day. The Thermarium is small, sauna and Turkish bath tiny and only three showers, so expect to stay in line especially on weekends or holidays. Natural water massages are cold and the hydro-jets very weak. Too many people are allowed into the Thermarium at a time so it feels like there is no space to relax. Again a pay per entrance not by day and residents at the hotel get a discount. Maintenance around the complex is generally poor as odours and smells are noticed all over and parts of the ceramics are falling apart. Water is cold in some areas. Public shower area has been recently refurbished. Breakfast was pathetic, pastries tasted stale, old and we found the bread old as well. One hot drink is brought to you. Boiled eggs were cold as if they were in the fridge. New Year's Eve party was very disappointing, food was poor, I noticed many people not eating all of their portions - which were small. We had to chase down the waiters to get more water and wine. The package had boasted live music for the night, but we spent the entire evening up to just a couple of minutes before midnight listening to people through karaoke. At midnight we were offered one half glass of Brut, but after dinner no digestives or other alcoholic drinks were offered. Area in front of the bar was nicely set-up with open fires but still completely out in the open. If their prices would be more in line with what is on offer, it would not be too bad, but paying the same rates (and sometimes more!) that I've paid in other Thermal and Spas with much better services leaves this one in the dark shadows. Seems that they try to sell more than they offer and fall short. Definitely not worth the money asked.
