Everything was need and tidy! He was a very good host, he welcomed us at the apartment, showed us around and explained us everything. He asked us if we are fine or if we need something some hours after arrival. Booked us a taxi for our departure. He could have showed us the air conditioning and how we can turn it on for heating. Cause the central heating system was a bit too weak for those cold temperatures. Still, we survived ;) and enjoyed the stay at his flat truly. Thanks Kirils!
