We had a terrific experience at Zach's great apartment. It is a really adorable place, squeaky clean, and perfectly appointed. My husband and I had our own room, separate but adjacent to the living room. The mattress was awesome and it was so dark and quiet that we slept in - so nice on what can be a demanding trip!
I have two gangly teenage boys and they really liked having their own space in the living room with the TV. They needed breaks from the non-stop museum march, so they explored the neighborhood, walking down to the park and fooling around on a scooter. The fold out bed stayed folded out the whole time and they lounged on it happily. They slept great.
The kitchen is roomy and completely equipped. It has the washer/dryer we needed, but I really want to emphasize the bathroom: gorgeous white tiles, thick fluffy towels, and spa quality toiletries! That shower head is so wonderful we are buying one for our own house and there is a deep, glorious tub for soaking.
You cannot beat staying right in capital hill: safe and convenient. So close that we often walked or Ubered (cheaper than the Metro with the four of us). The station at Eastern Market was an easy walk and we used it, too.
We'll be back!
