I stayed at Jimmy's place for about 3 weeks and I can say that this is an outstanding Airbnb both in terms of the place itself and the host. I will not list all the things the place has to offer (see the photos), but Jimmy clearly takes his project to make this into the Best Man Cave Ever quite seriously. (One thing the photos do not show is the large backyard.) I had a great time as a solo traveler, but I imagine the place really comes into its own with a small group of guests. The immediate neighborhood is very peaceful and it takes about 15 minutes to get to Vanderbilt by bike.
Jimmy and his wife Joyce were very hospitable and Jimmy went out of his way many times to help me out as a new arrival to Nashville (and the US in general) without any means of transportation and to make me feel welcome, which was much appreciated. Plus, he's an interesting guy to talk to.
All in all, my best Airbnb experience so far.
