Lovely area and beautiful property! The sign is hard to see because the writing is very small on it so you can't easily read it as you drive by. It says "Corte Domina" and not "Tenuta Corte Domina", which is what you might be expecting from your booking.
We had a nice large room with a high ceiling. They designed it so that the bed was in the middle of the room, and the shower placed behind it. This meant that the bed had no electrical outlets near it, so remember to bring an extension cord with you.
Linens were pristine white and comfy, shower was great, views were lovely and peaceful. This is Chianti country and is at slightly higher elevation than elsewhere in Tuscany, so there are more trees, fewer olive orchards.
The dining room is beautiful. The breakfast is great! The dinner was confusing. We were only offered an option of a 'tasting menu'. Not told what it would cost. Not told of other options. We experienced a very slow 2.5 hour meal of very tiny but tasty plates, charmingly presented by the hostess but ultimately not satisfying as a meal. More like a bunch of appetizers. For example the 'soup' course was a tablespoon serving. The dessert course was six teaspoon-size dots of pistachio cream and hazelnut cream. This menu cost us 75 euro each.
Meanwhile, another table was served a standard primi and secondi course, with full plates, in half the time that we spent. They had access to a menu that we were never offered, and left satisfied. Consider dinner in town!
