This place is cheap and, in theory, convenient. I chose to say here because it was the most affordable place that included a free airport shuttle. The motel itself is okay as long as you know what to expect (it's old and run down, not at all fancy, kind of dirty, not well-managed).
My stay was fine until the 7AM shuttle I had requested failed to arrive on time, and I ultimately ended up waiting more than 30 minutes for it to show up. The Super 8 has a deal with one of the airport parking shuttles, and apparently one of their drivers had failed to show up to work that morning. Fortunately I had enough of a time cushion that I didn't miss my flight, but the shuttle to the airport was the entire reason I'd chosen to stay at the Super 8.
If you need a cheap place to stay near the airport, consider this place but be warned that the shuttle service is anything but reliable.
