Stayed with John for a little over a month. Overall had a wonderful experience!
The location: Can't get much better than this for Capitol Hill. The apartment is within a walk's distance to the Capitol, Supreme Court, tons of great restaurants, the metro, etc. Never needed to drive or even use rideshares while I was there. Made my life a whole lot easier.
The unit: Perfectly comfortable apartment. The bed and couch are comfortable, the kitchen is nice for doing a bit of cooking during the stay. The whole unit was clean and in good condition too. Internet likewise worked well during the stay.
The host: John is lovely and all of my interactions with him were top-notch. He responds super quickly and was also very flexible in arranging a mid-stay cleaning of the unit as well as letting me get some mail delivered to the address.
Overall: Would highly recommend John's place to anyone looking for an easy, reasonably priced, comfortable place in DC. I'll be looking for the listing again next time I'm in town.
