Great spot! The neighbourhood is fun and has lots of amenities. There is a terrific breakfast spot right across the street, and fabulous dining for later in the day as well. Also a quick walk to the metro which is handy.
The apartment is beautifully appointed with a comfy bed (also the tallest one we've ever encountered but they provide step stools!). Nice to have Netflix and wifi. We didn't use the kitchen facilities but they looked excellent.
Perhaps most important of all, the communications before we arrived and during our stay were excellent. We knew that if we had any problems or questions they were there to help us. They were very flexible with luggage storage to accommodate our flight schedule.
We recommend Rob and Patrick's place to anyone travelling to Washington. You would be lucky to get this spot.
