Chris is a great host and very meticulous and great at communicating.
His place is awesome and was perfect for me and my family with small kids and our dog. Perfect place for my family that loves going to zoos. We literally walked there and back taking the Harvard Street bridge exit.
The stairs going up and down can be tricky, but my 6 year old girl had no issues with them as well as myself with some mobility issues due to my scoliosis.
Easy access using public transportation once you figure out public transportation- we used the two bus stops super close to the house- the H2 bus- to go to Columbia Heights or Cleveland Park and from them taking the subway or another bus to the national mall attractions.
I would love to stay at his house again when visiting DC.
