I booked a suite in Ken and Angela's house for 6 months to work at Vanderbilt University. Ken and Angela were really kind, responsive and accommodating, which really helped me throughout my first stay in the US. For instance, they took me to Publix when I arrived from Switzerland because it was getting dark and I needed to buy food for the next day. It was an absolute pleasure to meet them and to learn about Nashville through them. Also, the house was lovely, comfortable and really convenient for long term stays with everything you would expect (e.g., fully equipped kitchen, washing and drying machines). So, it was a great experience and I highly recommend renting for them!
