We were visiting the Arnolds and the location was unbeatable! The convention center is less than 5 min walk away, but it is noisy at night since the apartment is right on top of a restaurant so you can hear the music until late (earplug were provided).
If you are an international guest check in is slightly complicated since the door code information etc is only being shared by SMS and I did not have an US number, luckily my partner did hence everything went smooth.
Overall I would definitely book it again in a heart beat, all the amenities that you need in an amazing location!
