Beautiful basement apartment in Capitol Hill! It had everything you would expect from a great Airbnb. There was no pack n play, but the pull out couch worked well for our toddler (however it probably would not have been super comfortable for 2 adults). The other bed was great! Full size appliances worked well for the little bit of cooking we did. Even had a few extras like a washer and dryer, a Nespresso machine, and heated bathroom floors! Note that there are several steps to get into the apartment, if mobility is an issue.
Location-wise it’s right in the middle of Capitol Hill, about a 15 min walk from the Metro stops at Union Station and Eastern Market. Right on the bus line, though! Highly recommend getting a multi-day pass for the Metro while you’re here — the buses and Metro make it easy to get around. With public transportation, it takes about 30 min to get to everything in the National Mall area.
