Colleagues and I stayed at Scott's place for a conference at the Convention Center and it was in the perfect location, which was very easy to get to from the airport via the yellow metro line. An easy 10-15 minute walk to the convention center, or if the weather was bad we could take a 5 minute bus ride, or 1 stop on the metro. A large grocery store was also within walking distance and the kitchen was very well equipped.
The beds were comfortable and the showers were great. Scott provided lots of extra touches, such as makeup wipes, which was appreciated.
The street was nice and quiet, as well.
We would highly recommend Scott's place and will keep it in mind for future trips to DC.
