Great hosts. They were quick to respond if we had questions (I asked about recommended places for families with teens), but they were otherwise not present so we felt like we were staying alone. (The place is the basement apartment of their home with a separate entrance.)
LOVED the place- especially the fireplace and cozy feel and open kitchen with living room. Very clear on all their arrival and departure notes. And, most of all great price and unbeatable location (residential but so close to all you will want to do in Nashville.) As an aside, if you are Y members, the YMCA close by is totally amazing (huge with lots of equipment and super friendly workers there).
