Karina's place was great! Very clean and new, plenty of closet space to store luggage, and excellent location: 5 blocks from the metro, across the street from the market, in a nice neighborhood. A big perk was having a private bathroom just across the hall. Karina and her mother were both super friendly and interesting to talk with. We stayed there a second time when we passed back through DF, and would be happy to stay there again in the future.
