The place is quite comfy and relatively convenient. Only takes a few mins to Taksim square as well as the station. Roughly 8-10 min walk to the HAVABUS stop where you can easily take a bus from/to both airports. I've noticed that people in Istanbul talk with loud volume on the streets even during midnight so I was able to catch some noises even when the windows were closed. Didn't affect my sleep but I think someone who are extremely sensitive to noises should know.
