LolaSlaytor, the three main Pole Pressure sites in DC are; downtown, Capitol Hill, and Cleveland Park. Pole Pressure used to have instructor "bios" on their website, but with their expanding business locations I think that has been discontinued. I would recommend that you ask for Crystal as a private instructor. I personally haven't trained with her, but everything that I've heard about Crystal is very good. She's a great lady. I've seen her at competitions and she's a lot of fun to be with. Plus, she could give you lots of tips on places to eat, what to see, clubs, etc.
The "Exorcist Steps" are in the Georgetown area near the river. Lots of history, restaurants, and sight-seeing in this area. Ask one of the locals and they'll be glad to tell you where the steps are located. It's worth a few photo's with your friend.
Pole Pressure was the first studio that I went to when I started pole fitness. It's a very progressive, and well run organization. Unfortunately, the Leesburg, Virginia studio closed in 2013. The other PP studio's are a long commute for me. Have a fun trip. Enjoy DC and I hope you have a great time poling at Pole Pressure.
