My Fiance and I had the pleasure of staying at Tiffany's Guesthouse just this past weekend for three days. It was amazing! It was very clean and wonderfully decorated. Attention was given even to the littlest of details, such as the handmade soap in the shower and a few snack bars for a road weary traveler.
The guest house itself had its own car port and separate private mini porch area, so it really felt like you had your own place. Travelling to the downtown Nashville area took us around 15 to 20 minutes, but is a painless drive on mostly highways.
We enjoyed our stay and would definitely highly recommend it!
