The Hilton Garden Inn in Bethesda is located on a quiet side street a block away from Wisconsin Avenue. It's across the street from a Marriott Residence Inn, and there are other hotels in the immediate vicinity. It's an excellent location.
There is off street covered self parking in a neighboring garage that has a direct entrance to the lobby. The 12 dollar cost is reasonable.
The room I had was spacious an well-appointed, except for a Keurig machine that did not work.
The staff at the front desk are very hospitable and welcoming. The associate named Samantha, who has been mentioned in other reviews, represents the Hilton organization very well indeed. Vouchers for complimentary wine or beer are offered. Clear suggestions for where to find restaurants in the neighborhood are given.
