We spent 3 nights at Karl’s place. Overall that was a nice experience. Communication with Karl is great, he is an efficient host. Here is our viewpoint about the place.
Pros: the situation is great to discover DC. One can reach any major place within 20/30 minutes by bike. There is a city bikes sharing dock a few hundred meters away. The Bloomingdale neighorhood is great, with many restaurants around. The house is roomy and well equipped.
Neutral but good to know, the house is along an highly trafficked avenue, night and day. Not a big deal if you are urban, but if you aren’t you should know that the master bedroom is above the street. The mbr mastress is very firm, once again taste dependant.
Cons: the immediate neiberhood (1/4 of mile around) is undergoing renewal. Lots of road works and empty houses under renovation or abandoned, not very clean. We had city trash on the pavement just at the front door for 2 days, not so nice as smelling bad especially when the weather is hot.
