This hotel is located just in front of Katowice central station, and a bus from the Katowice airport also stops here. Check-in was smooth, and room is clean and comfortable. I really enjoyed breakfast. There are variety of "side" menus like charcuterie, fromage, hummus, honey from real honeycomb(!), etc.
Check-out time is 12:00, and this helps me. After a long flight, I wanted to sleep longer and got up relatively late.
