I had a great stay at Susan's and would recommend anyone staying in Nashville to book Susan's apartment. It's very cute and spacious, big shower, comfy bed and loads of space to store your luggage etc.
Despite it being a bit far off the city center it's easily accessible via bus (Susan provided all the info of how to get around the city - I chose the bus). I even walked a few miles through the neighbourhood which turned out to be lovely as well. A couple of nice restaurants just around the corner.
I really felt at home at her place.
