Robert's place is awesome, it had a real DC feel (as opposed to a hotel room), It made me feel like a local. Fantastic value for the location which is a walking distance to the Wharf, L'enfant subway which connects 3 major routes (so either zero or wayy less transfers required). Also, you can actually save more money just by walking to the Mall (its like "right there") and from the mall you can spread out to other interesting points such as Ford Theatre and such. Take it from someone who was on an extreme budget, you would really enjoy this location. Robert also facilitated early check in for me since I arrived quite early in the morning so that was extremely awesome.
He also provided some basic foods which help to get you started in the day. You also get sattelite tv, washer and deyer a sofa bed and a private entrance!
I wanna give out a shoutout to Barb who helped me accomodate quite nicely!
