John's place is great and his hospitality is even better! While I never meet John face to face (my own introvert tendencies), his communication, his printed instructions and advice, and the goodies he provided are the best I've experienced. My favorite parts of his place are...
1) The LOCATION! Only a block from the nearest Metro stop and 10-15 minutes walk to either the National Mall or a huge grocery store (in opposite directions)
2) The washer and dryer. Small but so convenient.
3) The complimentary food he provides. It made it so easy to feed my tired kids in the morning without overthinking.
