I did not stay in the unit, but booked for my mother and her partner. She is a little picky at her age (over 60), but she enjoyed the stay. Some things she noted:
The amount of light for an English basement is very good. There were some fixtures that seemed to be in need of cleaning (layer of dust), but overall the space was enjoyable and well equipped. The layout and proximity to H st, Union station, and Capitol Hill, were perfect for their needs. It IS possible to hear sounds from the home above (e.g. pitter patter of little feet), but mom raised 5 kids herself and it didn’t bother her. Aside from a small issue at check-in, which was quickly resolved by Barrett, the stay seemed great for my family.
