We checked in on August 30th at midnight at 12:01 am. We were at SF by business and had an early morning conference. We had a very long flight to san Francisco and were so exhausted , so we wanted get to bed and so to sleep asap. to our surprise when we arrived we found a group of people around 5-6 are having a party with alcohol , loud music and girl's screams downstairs. In host's policy says about quiet hours after 9 pm. The load party ended only in the morning. we immediately wrote a ton of messages to the host and explain that we cant sleep because of SUPER LOUD PARTY are going on downstairs . that we had a long flight to SF and we wanna sleep. Asked the host resolve the issue asap. He didnt respond to us. We recorded a few audio as a proof which recorded load music, party and screams. Enrique is in charge, but he didnt take a control under situation.
