Clean, spacious place right in the heart of Georgetown. We enjoyed walking down to the waterfront, and availing of the many cute little restaurants in the area. Our toddler was a fan of the space and loved watching buses from the window!
Marsh was responsive and gave us a very detailed guide to the area.
The only downside was the restrictive street parking, which seems quite common for DC. It's not a problem if you're planning to be out and about for most of the day (parking is free past 6pm), but you know get two hours in the entire area during the day which means you'll need to find paid parking if you want to leave your car behind.
