Our room was a Suite, when we first arrived in our room, we noticed a loud rumbling sound coming from the interior wall in the Bedroom. I did walk down and talked to the front desk, the gentleman, I bought him up to the Room 309. He heard the noise, determined it was coming from the mechanical /electric room adjacent to the bedroom. He told us that was from the Elevator running, the noise was from the elevator usage, every time someone used the elevator the entire wall and room shook. We went out and bought a box fan, had the fan on full and still did not mask the noise. We didn't much sleep both nights. This should be looked into ASAP, so other guest is not impacted.
