The "Eastland Compound" is is a great place to stay. It's finished space above a garage that offers great privacy and comfort. It looks to have been finished about 1 year ago and it was thoughtfully and very well done; a great space to come back and relax after a busy day of sightseeing and honkytonking.
It's not downtown Nashville, but don't let that sway you as it's only a few minutes drive to most places you'd want to go. Plus, there are plenty of places within walking distance to eat and relax.
Matt, your host, is very helpful and responded quickly to communications. We think this spot is great value and, hands-down, beats any hotel.
