So I generally consider myself pretty easy-going, good at sleeping just about anywhere and through most things. And I didn't need/expect much -- pretty much just a place to get dressed for a party and then to crash for one night. And it almost fulfilled exactly those needs. The room was as described, and while there was noise from the subway train, it wasn't too bad. The walls are a little thin, and some neighbors were having a loud party, but it was over by midnight so totally reasonable, it WAS a friday night.
but what is NOT reasonable was when my host (I'm assuming, I never actually met her) returned at 3 am with someone else, and proceeded to make a TON of noise for the NEXT THREE HOURS. Some intimate noises, some shrieking, some laughter, some arguing. It was pretty ridiculous, and meant i had a terrible night's sleep. Granted, I never actually got up and asked them to stop, but I was trying to sleep through it, and anytime I was about to get up and got really angry, things would get quiet and I kept thinking they were about to go to bed or something...only to hear another shriek like 20 min later and then the whole thing started again. Plus I really don't think its asking too much for my host to be aware that she has a paying guest who might be trying to sleep at 5 am.
It was a very, very frustrating experience.
