Staying in Heather's home might be the highlight of our short trip to DC! My 7yo daughter loved all the exercise equipment Heather has available. Heather is a gracious, informative host, and her home is stunning.
Parent advice: Heather's place - as fantastic as it is - is not ideal for people with toddlers or preschoolers. Her collection of artwork and photographs may be too tempting for kids who cannot keep their hands to themselves. (This is purely my own opinion! Heather is too polite to say anything of the sort.)
Metro advice: When exiting the Eastern Market station, first orientate yourself at the intersection of 8th Street and Pennsylvania Ave. Then, cross to the park on the opposite diagonal corner. (My daughter and I came to call this the "baby park" because it provided a toddler play area.) Keep crossing through this park to reach it's opposite diagonal corner. Once past the toddler equipment, you'll find South Carolina Ave SE which will lead to Heather's front gate.
