Microwave at the end of our hall was not clean. I suspect a guest left it that way. That said, it was dirty when we arrived after 11pm (and needed to use it) and it was still that way when we checked out in the morning. Staff should be periodically checking it even if it's late at night.
Staff, room, breakfast were all clean.
I would have appreciated a lactose free option (milk/yogurt) with breakfast. The rest of what was there was fine.
