I stayed here while attending a convention at the center downtown. Tyler was attentive to questions, and provided great recommendations for local food. The apartment had a little balcony, a coffee bar, and was nicely decorated. The washer and dryer - right in the very large closet between the bedroom and bathroom was a real gift. IT was also quiet for sleeping at night. As a woman traveling alone, I felt safe too.
The complex amenities were nice, including a good sized workout facility and pool with hammocks. I wish the PGA simulator had been working right, but geez - the fact there is one is a bonus, so no complaints there.
One tip - do not rent a very large vehicle, as the parking garage has a lot of tight turns.
All in all it was a wonderful stay, and I highly recommend it if you are planning to stay in Louisville.
