Kevin's house is amazing! There is so much more that could be said than what is in the ad. Where to start, okay, the neighborhood is pretty quiet and laid back. It's set in a pretty nice little residential community. You'll find yourself a few minutes drive from most major stores and restaurants (just enough to enjoy being away from the hustle and bustle of the day to day grind, but close enough to get to a gas station or five restaurants in five minutes).
Kevin graciously offered use of his fridge space and laundry facilities which was a huge help for me since I was coming to Nashville to attend the Warrior Dash (a mud soaked race that leaves people and clothes just a tad less than fresh).
The room has an attached shower and bath combo. The bathtub itself is larger than most standard models though (which was also nice after the Warrior Dash). I brought my own, but Kevin provided soap and a number of other toiletries on the counter in the bathroom. He also provided towels and wash cloths. The room itself is pretty spacious and can fit a family's amount of suitcases in one corner while still being able to move about the room. There is a mini refrigerator if you'd prefer to keep your water/drinks or leftovers upstairs which was really handy. The room receives ample lighting between a ceiling fan and a couple lamps, and the fan can help to cool it down if you don't wish to change the air conditioning at the wall downstairs.
The bed is amazingly comfortable. I'm not sure if it was the sheets or the mattress or what, but I haven't slept that well or soundly in a long time. It was definitely a very nice experience.
Overall, if you are coming to Nashville for business or pleasure, this is one of the best deals you are going to get hands down. It is comfortable, quiet, and welcoming while still being within 20 minutes of downtown (including traffic). 6/5 Stars.
