As mentioned, the guest room is around the back of the Halcyon Spa. The pad has ample parking for two cars. When we arrived, everything was perfectly clean. Additionally, the kitchenette was well stocked with bagels, cream cheese, parfaits, muffins, and coffee. Do not plan on making any elaborate meals here, as the kitchenette does not have a stove or oven, and only a mini-fridge. We ate out at the wineries for some meals, and brought pre-made salads which we enjoyed in the room.
The bathroom is spacious, featuring multiple shower heads and a heated floor. The use of the sauna is an added bonus. And the king-sized bed was VERY comfortable.
When you spend a weekend in Augusta, there are bunches of different BnB options. We've tried most of them, but this might just be our favorite.
Side note: get a reservation for a massage at Halcyon. The quality is equal to any high-end spa at a destination resort, at a fraction of the cost.
