We spent three nights at Mt. Vernon Square B&B. Our room was spacious, comfortable, and well-appointed. Keith is an excellent host and made us feel very welcome. The breakfasts were delicious, especially the banana pancakes! Oh, and the cornbread and the eggs with spinach and feta cheese...Yum!! As for the location, how perfect! The house is a block away from a large grocery and a wonderful restaurant, and the Metro is a short three-block walk through a lovely neighborhood of historic townhouses. Union Station is nearby as well. This is an ideal location as a base for exploring Washington DC for adults, but probably not for children.....the temptation to slide down the stair bannister might just be too much!
