The room provided by Dennis is clean and in an ideal location to visit the National Mall easily. The home is also located close enough to the stadium where the local baseball team plays to make it an easy walk over. The entry to the home and communication were also fantastic.
The only downside was the street parking was full and I wound up parking at a pay lot 5-6 blocks away. I checked parking upon leaving the next day, as I thought it may have been attributed to the baseball game the night I was staying, but everything was still full. Also there seemed to be a street party going on outside so bring your earplugs!
Overall though the location was a good value and I would have rated 5 stars if the street parking situation wasn't a problem.
