We enjoyed our stay at Henrike's place. The place was as in the pictures, spacious and with everything we needed. Henrike was an awesome host, very responsive, and actually meeting us and chatting with us, which we actually love to do with our hosts.
We are a family of four (two kids 7 and 9), one kid slept on the couch and the other one on an inflatable mattress, and both of them felt very comfortable. Also, there was a swing-set and a trampoline that our kids enjoyed while playing with Henrike's kids.
Very quite and family-friendly neighborhood, about 10-15 minute walk to the NoMa metro station, which was very easy to reach, we used it all the time to get to and from other parts of DC (nice playground half way to the metro station) Also, there are 2-3 of bus stops, one right in front of their house, another around the block. Between the metro and the bus you can pretty much get everywhere in a very reasonable time.
We'll definitely stay there again if we return to DC
