Tran's place is in an older house, like most in the area, and it seems the house was dived to accommodate several independent apartments. It was very clean and easy to access. It is located half a block from a Metro station, and within walking distance to Congress, and the east side of the National Mall.
Tran was quick to respond to our messages, helpful, and clear with instructions. We had an emergency on our first day there, an she was gracious and understanding, and let us check in earlier. That is the most important part for us, we felt welcome and safe.
