Tamar, I truly enjoyed meeting you and having you as my guest. You're just a genuine and warm individual. I took your comment about the inconsistent noises at night and added a "white noise machine" that's supposed to re-create the calming sound of moving air to block out disturbing background noises. I also out a fan in the guest room for those warm balmy nights in San Francisco. It may not get much use but it's there when needed.
Hope to see you again soon.
