We just returned from a three day trip to see the cherry blossoms. When we made the reservation at the Hyatt House, the cherry blossoms were supposed to be in full bloom. Unfortunately, they were not. The lack of cherry blossoms did not dampen our enjoyment of the Hyatt House in Falls Church. Recently opened, the Hyatt House is a pleasure. The staff were all friendly and very willing to help. The room (king bed without a sofa bed) was large and well appointed. The free breakfast was typical of other Hyatt House facilities. In other words, it is very good. All of this at a very reasonable price of $93/night.
If you want a nice hotel with easy access to the Metro, this is your place. The walk from the hotel to the Dunn-Loring Metro stop is about 12 minutes. The stop is on the Orange line so if you are going to the Mall, it's a 30 minute ride to the Smithsonian Metro stop on the Mall. Directions to the Metro stop: from the hotel take a right (Lee highway) and follow until you reach Gallows Road (2 blocks). Turn left onto Gallows Road and follow for about 5 blocks. The Metro stop is on the left side of the road just before you reach a bridge over a highway.
