It's apparently part of the Angala chain and maybe that's why I felt let down -- sometimes haughty/indifferent attitude at the front desk and a sort of generic, cliche "wine country getaway" feel to the whole place. It reminded me of some similar Napa Valley properties 30 or so years ago -- after the initial rave reviews they moved into a sort of stasis that nonetheless did not prevent them from attracting tourists, honeymooners and conference-goers for years to come.
However, the Relais is convenient if you want or need to be in the Madonie mountains or near Cefalu.
The lobby is nicely decorated. My room seemed sort of "modern posh country generic." The "reading room" or "library" that looked so cozy and inviting from the outside had a sort of over the top roccoco Versace-esque feel on the inside -- with piped-in Italian pop music to boot! Not my kind of reading place. The breakfast was only average and the staff there seemed harried.
I stayed there for 2 nights in mid-October.
