This place is A+.
The host (Nicole) is there to help out if you need anything and totally invisible if you've got everything in order. The location is fantastic whether you are on business or on vacation--tons of walkable amenities as well as easy access to metro and car service.
The place itself has a super-cool layout for a basement unit and is perfect for solo travelers or small groups (2-4).
It's also a great place to get some work done--creative, corporate, or otherwise--due to the relative quiet (even though the neighborhood is bustling), rock solid internet, and some good tables/desks.
Highly recommended. Will likely be back.
