This was the perfect place for our vacation in Washington DC. It is a small walk to the Metro (about 15 minutes), but then a very short commute (another 15 minutes) to anywhere you would need to go to in DC. This worked out well for us, because we could leave our car in front of the unit all week (ask the host and he will get you a street pass) and then take the Metro around the city. Plenty of street parking. It was a very quiet neighborhood and we all felt safe.
The place was very well maintained, and plenty of room for the 4 of us to relax after a long day on our feet. Very nice bedrooms and bathrooms.
