It’s actually surprisingly not bad at all - I’m pretty impressed with the soundproofing. Not dead silent, but the windows are good enough that there’s really just muffled background noise.

The other thing that I noticed is the cleanliness of the windows. I find that hotels and apartments with good views often skimp on window washing, which negates the benefit of the views. Kudos to management here for making sure that the views aren’t marred by grimy windows!
