We stayed a single night. We didn't get a chance to meet Michael but we got the greatest introduction by two of Michaels assistens. I did however communicate with Michael by mail a few times and on the phone once. Always responsive and kind.
The house is wonderful decorated, very clean and nice. We didn't use the outdoor facilities. You do hear the planes in the room but the airport is closed during the night I believe so unless you go to bed early or like to sleep late it shouldn't bother you.
Be aware that you are presented with a legal document you need to sign upon arrival. Complicated stuff. I recommend that you request the document send to you in advance so you can go through it carefully before you arrive.
