Thank you Home Sweet City for a perfect stay! Everyone: if this gem is available, book it!
Pros:
Arguably the single most perfect location in DC (amazing shops, cafés, bars, and restaurants literally across the street; safe area; White House, etc. actually walkable);
Spotlessly clean, lovingly decorated, well-equipped apartment;
Great hosts, neighbors and owners.
To us, It truly felt like a home away from home.
Cons: We did have to leave after all. :-)
(Possibly consider bringing a sleep mask because the area is relatively bright at night.)
