We had a great time staying at Lindsay's. Wherever we had a question, Lindsay was immediately responsive and very helpful. Adjustment is very comfortable and in a great location.
As others have said, you can hear the upstairs neighbors a bit, and the bathroom door is frosted glass which is a bit strange, but since we knew what to expect and weren't home much, neither was an issue for us.
Tip for future visitors who come by car: there's plenty of on-street parking for evenings (and presumably weekends, though we were only there weekdays). It's 2 hours except for residents during the day, but there is a garage nearby (8th & H - maybe a 10-15 minute walk) that has all-day parking for $5. We moved our car there by 8 each morning then spent the rest of the day getting around DC by foot and metro/bus. Time-limited Street parking ends at 8:30, so we'd pick up the car and move it back to the street around 6:30 before heading out to dinner.
