Our group had a DC get away on Fourth of July weekend. The space feels like a well managed high end hotel.
The rooftop was perfect for seeing the wonders of fireworks around DC, a nice clean modern space perfect for a private party. You can see the capitol fire works in distance, and many nearby at the same time (about a 15 different private fireworks).
The space had unpleasant visitor right before us, causing lockbox to be lost and space to be heavily scented with tobacco. John was very responsive, and quickly accommodated to ensure check in was as smooth as possible, and there was really no delay in our ability to get into the space. There is very nice fan and A/C in a modern space, and we could air out the tobacco smell as much as we could during the stay. The unit is on the top floor, expect to walk a lot of stairs, no elevator access. The unit has two floors - first floor with a small room with foldable futon, a nice full bath with a bathtub, fully furnished kitchen and living room space. Second floor with master bedroom with king size bed, walk in shower / full bath, access to the rooftop patio.
Parking: there was private uncovered space for two compact cars in the back of the building. This was very convenient for us!
Overall we had a good time. The airbnb adds taxes, cleaning fee etc and can add additional $100 to each night to the face value (amounting to a little over $400 per night) - it was unexpectedly more expensive than first expected but may be manageable if splitting cost multiple ways with guests sharing the space.
