The ad describes the room and the environment well and the pictures reflect reality, i.e. you get what you want to get. Dawn is a nice and friendly host who pays attention to your needs; whether you have questions about transportation in DC or in need of hangers for clothes, she'll help you.
As a runner, I found the area perfect for jogging, Rock Creek Park is only a minute or two away. Also, buses run frequently to Silver Spring and downtown DC, too. I look forward to staying at Dawn's again in the future.
