We were there for a VERY short stay...checked in at 2 am and flying out at 10 am. Arriving exhausted, it was SO nice to be greeted warmly and quickly. Room was gorgeous, bed was very comfortable. Nice hot shower in the morning. One of the things I really like in a hotel and this Hilton Knoxville Airport has it, is the separate sinks....one in the toilet/shower and one outside so that I can brush teeth, put on makeup, etc while my husband takes his shower.
The only reason I didn't give it 5 stars is because the parking lot is across the service road and in our case, arriving so late, the only spots open were quite a distance to walk. And there is no complimentary breakfast. (It always amazes me that the cheaper hotels offer this but the expensive hotels don't.) They have what looks like a very nice restaurant but we didn't have the time to sample it. Also walked by their pool area when we were leaving and it is absolutely beautiful.
This was a very nice hotel....I was disappointed we couldn't stay longer and enjoy the amenities.
