Stayed here for a weekend with a friend to see DC.
The location is amazing, and walking from there to union station you see all the sights and can eat and drink in great bars.
We didn't see the host once, but everything we needed (parking permit, second blanket) were organised and delivered even when we were out. Communication via text or calling was excellent!
Apart from the musty smell and slightly dirty floors/shower (just dust) this is a fantastic spot!
