I stayed in Kathy's house with a group of people to attend a conference in Nashville. The house was very clean, peaceful and we had everything we needed. The location was safe and the distance to the downtown by car was as described in the ad. Although we didn't see Kathy personally, we were received by her son and communicated online with her and she responded quickly to our questions, even before the trip.
The only thing I didn't understand was an extra fee charged after we left for cleaning all the bed linen, as we were supposed to had it already payed in the cleaning fee item at the moment of reservation.
Anyway, I would definitely recommend Kathy's house.
