Dennis was a good host who promptly answered any and all the questions that I had about Washington. Spent three nights in the apartment and exploring the city. Apartment is about a half mile from the metro station.
Room itself was exactly as described. Small, but definitely large enough for one person. Upstairs was a tad hot, but we were in the middle of a heat wave, so definitely understandable. Only real negative was the location as the neighborhood was not the best, but would still recommend. Overall a good experience.
