The air conditioning wasn’t working, so it had to be replaced. This delayed us from going out to eat and getting settled in. After the maintenance worker installed the replacement unit and it didn’t work, he reinstalled the old one, but it began making a loud squealing noise. When I asked about it, he said it was probably the fan. I thought the noise might stop while we were out, but when we returned, I could hear it before even opening the door. I recorded the sound and went to the front desk, and they ended up transferring us to another room.
