Pros:
1) The location is fantastic and within walking distance of the National Mall, which was the main draw for our trip. The apartment is in a safe area, and we were able to park directly in front of the building.
2) The hosts were very quick to respond to messages and were able to accommodate a last-minute change involving our parking pass, which was a massive relief.
3) The hosts left a laminated list of "house rules" and recommendations for local attractions that served as a nice jumping-off place for sightseeing and night life options.
Cons:
1) The amenities on the listing notes that free parking is available on premises. Though parking was provided, I was notified upon booking that there was a $50 fee for obtaining a parking pass. This information is disclosed in the "house manual" section after booking, but as free parking is advertised at the top of the amenities, I was surprised to learn that there was an additional charge. Depending on your budget, this might be worth considering when looking to book a place.
2) As noted by other reviewers, the hosts have small children, and the walls are very thin. The laminated "house rules" list does encourage guests to get in touch should they have concerns about the noise level, but it seems awkward to put the expectation on guests to complain to the hosts about their children.
3) Though the apartment was generally clean, there were large stains on the futon cushions.
Verdict: This apartment is relatively budget-friendly, and depending on your priorities, can be a good option for staying close to the action in DC. My friend and I were unfamiliar with the area and strongly prioritized safety and proximity to sightseeing during our trip. If you're in a similar situation and aren't deterred by the cons, I would recommend staying for a weekend getaway.
