This was a great local spot to cool off! We were staying in Impruneta, and this was recommended to us as it was nearby. The pool was very large and there were many chairs and umbrellas by the time we got there, about 11am on a hot Saturday.
They do not allow any outside food or beverage, but they have a great restaurant there with very decent prices.
If you go, you will need to bring a towel and swim cap. They sell caps there for €3. Mandatory even for men. Upon arrival I inquired about a towel and was told they do not have towel service, then another man said said we could rent it for €3 each. The cost for the day was €15 per person for a bed and umbrella. That gave us all day at the pool.
All the pools in this area seem to required swim caps. I was really disappointed by this, however, it helped to keep me from burning my scalp while playing in the pool. I guess that’s the plus side!
