We had a two days stay mid October at Poggio ai Santi. The weather was great and could eventually enjoy still of the beach.
Poggio ai Santi location is wonderful and all the staff was more than fair with us. We eventually make friendship with the owners who told us how they slowly build their small paradise.
They are used to invite their new guests to a welcome drink, which is a very good opportunity to know more about Tuscany.
By the way, I also see how some people can be rude and the patience the owners need to have with some: a couple (probably in their late 70...) arrived at the drink without greeting anybody not even the owners, complaining about the temperature (it was 19 degrees at night...), requiring extra heaters, dinner at 19h30 when the restaurant opens at 20h00 and... (believe us we were shocked for this...) to change the music which did not fit their taste (and we loved that soft jazz...!). Traveling sometimes allows us to catch exactly the kind of attitude to avoid. And the owners were just supporting all this with smiles and trying to solve.
