Hello Ciril, thank you for your comment :) About the bed, its the first time I hear complaints, it's pretty big, we provide two covers, and most guests were pleased with it :)
About the parking place, there are five spots on the parking lot, and sometimes in high season it might get crowded. However it's not a problem to place the car somewhere on the lot, even blocking other cars and just leave a note (on your windshield) where owner of the other car can find you. If they need their car they will ask you to let them out and you can take their place.
Not the perfect solution, I know, but parking spots are problematic everywhere in Zakopane in high season :)
