Unfortunately for me it was a terrible experience. If you want to sleep, then look for something else.
No insulation, you will hear everything, even people chatting in the street.
In a month, no night's sleep. The upstairs neighbor lives at night, so you will hear his every step, creaks every time he moves at home, music. And starts from 1am-2am. You will live stressed during your stay. Even if you manage to sleep, you will be woken up at 3 or 4 a.m.
Blueground customer service was nice, but they can't do anything. Rather, they have a role to reassure people instead of taking action. They don't offer any other solution : refund or relocation. You must submit and shut up.
I paid 4000$, They ended up ordering me a 20$ noise machine from Amazon to help me sleep, yes, they dared.
Thanks to Airbnb, who have been there during the whole problem, and who have made a gesture, even if it is symbolic, I appreciate it
