The Hilton Garden Inn Rockville - Gaithersburg is a very nice place to stay offering very good accommodations. The lobby was very nice and comfortable. From the very start service was very good. The HGI was very clean and housekeeping was top notch. We are not a fan of the Sleep Number beds, even after this being our second experience with this offering. We did not have an opportunity to use the other services so I cannot comment on those services. The one thing I would recommend is that you request a room on the upper floors and to the rear of the road. We were disturbed by the road noise, even on the third floor of the HGI the road noise was loud. Give the HGI a try, you will not be disappointed.
