We ( a couple in our early 30's) visited Washington over the Easter break and stayed in the Cozy Private Suite for 4 nights.
Linden was a super host, who made us feel very welcome and even provided yogurts, coffee and cereal bars in the room on our arrival.
It is very clean, tidy and comfortable room. Location is very good. Its close to H Street with loads of bars and restaurants and only a short 20 minute walk to Capitol Hill. The neighborhood is very quiet and safe. Would definitely recommend this property.
