Jeff's place is great, and he was excellent and communicative host. The apartment is perfect for a couple, a single or three close friends. It's walking distance to a supermarket (with liquor store) and a handful of good bars/food spots. The bed was comfy, the air conditioner was great, and I feel like the place is in shade for the whole day in any case, so heat I summer isn't a huge problem. The neighbourhood is full of gorgeous craftsman houses and the neighbours are friendly.
Jeff was flexible in his arrangements and allowed me to spend an extra two nights at the end of my stay. That's how much I loved Nashville.
If you're in town on a Monday, check out the Station Inn. It's a venue in the Gulch that has one of the best country bands you'll see.
Cheers to Jeff for an awesome stay.
