I have always enjoyed my stays at various Springhill Suites and the Louisville Airport location is no exception.
Although located off the north end of the airport, flight traffic was minimal so noise was not a problem. It is located an easy 10 minute drive (with light traffic) to downtown and a half mile walk from the Kentucky Expo Center, which I would suggest walking to, since parking is $8 for a car and $20 for a bus.
They have two public use computers and a printer for accessing the internet but don't expect to use them for anything more than printing your boarding pass as they are slow and the monitor's small.
Breakfast offered a variety of hot and cold items although seating can be limited depending on what time you get there.
The hotel offered a very friendly staff, clean room, and a great night's sleep.
