Hi Mark! Just wanted to let you know that I ordered a rug for the dining room yesterday. I hope that will take care of the chair noise above on the hard wood floor for the guests below. It's usually just me up there and if there are guests staying while I am away I tell them they need to stay out of the dining room past 10pm. I'm so sorry that the guests from China didn't understand this. Lost in translation I guess. I hope you'll come back and stay sometime. I feel terrible there was an issue. The new rug should help a lot.
