The Courtyard and Residence Inn are connected, and share some facilities. We stayed at the latter for a night prior to an early flight. The room was pretty warm, and the A/C wasn't working, but the engineer got that fixed, and all in all, it wasn't a bad stay. The kitchen is adequate for a longer stay, but be forewarned that there is no fan to exhaust the cooking odors, so go easy on the garlic.
I didn't find it as quiet as some others have said, but I was on the airport side.
