There are few places as aptly named as this Urban Sanctuary, and it's all thanks to it's wonderful hosts. My wife and I stayed here for 4 nights and were progressively more amazed at how great it really was.
Check-in was a breeze, and upon walking into the basement room (which is much larger than I'd expected), we were greeted by a bottle of wine and a ton of information to help make our visit to DC great. There were lots of great restaurant tips for various locations in the DC area, as well as a guide on what the best delivery to order in. It also has a few guidebooks to help plan your visit.
This place is walking distance to lots of great restaurants, bars, and the Metro. The neighborhood felt very safe (we had no issues walking around at all hours).
Best of all, the hosts are very quick to respond. My wife and I had an amazing time staying at the Urban Sanctuary!
