Horrible experience, I was stuck inside bathroom but I never lock the door. Inside ventilation fan working weak, I stand inside the humidity,airless confined space more than 1 hours for the security coming. I feel dizziness and headache which might due to
Luckily I have taken my phone which save me in trouble Otherwise don t know how Long time I will be stuck inside this 3m2 bathroom.
The security told me that the door was stuck due to air lock? Which means the facility got serious safety concern.
So far the customer service manager only said will provide me 25% reimbursement for their fault. Which means I still need to pay for this terrible room and hotel experience?!!!
PS, after the indignant complain, customer manager said will offer 50% for one room one night bill.(I book two room together, and both room have facilities issue, the other room #691 basin sink faulty and dropped). After I feedback all this issue by hotline and face talking, they just give me 50% reimbursement for one room without any apologies.
So bad experience and disappointment for Millennium Biltmore Hotel Los Angeles. Poor facilities poor services and follow up.
I means, it is 4 Stars Hotel, in that way I should get the same standard services which quality my pay. For this issue, I total call more than 18 calls for saving myself and feedback the issue. Engaged line and no body pick up.
