Had to do the grotto as a once in lifetime experience. been there and done. The grotta Gusti is a lavish spa modern and clad in white and green marble throughout. the staff at reception was friendly and nice. The thermal pool was the best, warm and the forced air in the curved walls (with body sized seating) was awesome... More

If you are going to be in Tuscany, between Florence and Viareggio, I highly recommend you treat yourself to a half a day, an entire day or a few days at the Grotta Giusti Spa! I have been visiting this Spa for several years, and between the service, facilities, and food, it's a nice break from all the touring. The... More

And then we had the salt scrub and candle massage-so soothing and relaxing. Just note, when you book, make sure you are clear on your entrance time as it does take 50 minutes to... More

Did't like the swimming caps and the cotton robes but the pool is heaven and the sauna cave like nothing else!

Still, it's interesting... More
