Usually, an ad that you see on the web is nicer than reality. This is not the case with Margot's airbnb. While the picture shows a good place, in reality the place is great. It is equivalent to a sweet in a 4 star hotel, but cheaper than a regular room in a hotel. The neighbourhood is also very nice. The location is walking distance from Union Station from which one can go to downtown NYC in about a couple of hours, and you are therefore very close to NYC door-to-door. Union Station is also pivotal in taking a city tour on a hop-on-hop-off bus in DC, and is also a place to all destinations in DC.
Besides these many features, the best feature of all was the landlord and her family. They seemed ready to go out of their way at any moment in order to meet my needs.
I could have never expected a better deal.
