Me and a friend stayed at Kurts house during five days when we visited the 2014 CMA festival.
Kurt is a really friendly and good host. We had dinner the first night and he showed us around the city. We got lots of information by talking but he's also written two A4's with good to know stuff about the surroundings, house and city in general.
All in all we have nothing but compliments, it's a nice house, parking available, excellent host, close by the city (we walked all days but one), safe area, quiet.
Highly recommended to others staying in Nashville, it felt like more like staying at a good friends house.
