We spent our first night in Nashville here since we landed late and didn't want to head downtown. They provide a free shuttle from the airport - you can either wait for it with the other shuttles or call from the phones inside the terminal.
It was everything you'd expect from a Sheraton. Comfortable and clean. We had an issue with our air conditioning not turning on and they were in the room to fix it within minutes. They offer a $10 per person shuttle downtown but if you are travelling with a group it'd be better to take an Uber car for approximately $15. The ride is about 20-30 minutes depending on where you're headed.
Definitely would stay again if my trip wasn't centered around downtown Nashville. Would be a good home base for touring the surrounding areas.
