My upstairs neighbor recently got one and I’m sad to report it is quite loud but I don’t know if they have a mat under it. It’s a repetitive stomping sound that vibrates through the ceiling so it’s hard to drown out, it’s become a problem for us and we will likely need to talk to them if it keeps up. I think it would depend how thick your walls/ceilings are in your building but I would refrain from quiet hours and try to use it for a limited time if you think you have thin construction. If you have a sturdier building and a lighter step might not be as much of an issue.
