LOCATION, LOCATION, LOCATION. This is literally one block from the Library of Congress and 2 short blocks from the Capitl, 3-4 short blocks from the Supreme Court. It's a quiet and super safe neighborhood with eateries, bars, scooters, bikes everywhere.
The Metro is a tad farther than we expected (10 min walk either way), but with the Capitol so close, we opted to walk everywhere or scooter/bike.
The house is generously stocked with everything that would make your stay comfortable and convenient.
For our group of 8, the 4 full-baths were so convenient, and the updated bathroom had strong and hot showers. The beds were comfortable.
There is multi-layers of carpeting throughout the house which detracts from a clean-design, but I think it's there to keep the sound to a minimum from the downstairs unit (we were told to keep our voices down at around 10:30pm when we were watching a basketball game on the downstairs TV).
While it was a bit expensive for us, being able to have our family all together under one roof with a common space to gather was priceless and something we weren't able to get in a hotel. Also there is a full bedroom, bathroom on the main, ground floor which was critical for our party with an older family member; all the other bedrooms/bathrooms were upstairs.
Don't expect the Ritz-Carlton, this looks and feels like a large comfortable family home.
