Katka saved me from a sleepless night by providing me with an emergency couch during a long journey, on my way back from Russia. She was very kind and easy-going despite of the fact that I deprived her from sleeping in the late evening, when I arrived, and the early morning, when I left:-) I appreciate it very much, Katka, my couch is always available for you! Her dog is really very friendly and well behaved:-)
