Hudson Heights/Fort Washington

Hi everyone, I just found a really nice apartment in Hudson Heights on Fort Washington Ave (around 188th). I like the location, but all the windows in the unit face Fort Washington Ave which has the M4 bus. I am sensitive and am concerned about noise. Does anyone have actual experience living around here? Does the bus running by your window bother you at all? As far as I can tell, this is a quiet final stretch on the M4, so traffic is light, but still the idea of having a city bus under my bedroom window is sort of holding me back. Any advice will be appreciated. Related question: Bennett vs. Fort Washington Ave? Bennett is below the cliff, but have no noise issue (i.e. no bus) whereas Fort Washington Ave is higher up, but has the bus route. Any thoughts? Thanks so much!
