We stayed in the 611 apartment for 2 nights from September 30 - Oct 2, 2017. The apartment was clean, and ready for our stay. The two beds and pull out couch were needed for us, as we had 6 adults staying in the apartment. We had a difficult time finding the bedding for the pull out couch, and never were able to find extra pillows. (Having these left out for guests who will need the couch may be easiest?) The apartment looks over the water, and is in a quiet area. (You do also look at a large construction yard - there are planes and train traffic).
There were some parting rules for the apartment, but they were easy to manage. Towels in the bathtub, garbage taken out, and tidying the room. There was an extra charge if we didn't do these things.
Overall, we had a good stay at the apartment and enjoyed Nashville!
