Carli's apartment is in a great location, very close to the Foggy Bottom metro station and several restaurants. We were in constant communication with Evelyn leading up to the trip, and around our departure as well. The building was older, but nice, and seemed very safe. We never felt uncomfortable during the four days we stayed there, including the nights we walked back late. Evelyn met us when we arrived to show us around and answer any questions. There was plenty of space for the two of us, and while we didn't use the kitchen it seemed adequately outfitted if you would want to cook a meal. The only negative (the reason for the 4-stars vs. 5) is the bed. It was uncomfortable and neither of us felt like we were rested. Other than that, everything was fantastic!
