Airport transit visa are only good for short stopovers while you are waiting a few hours for your onward flight in the airport's international transit area. However, hotel accommodation is only available outside the transit area. Please apply for a regular tourist visa if you want to stay at the airport overnight.
On the other side if your final destination is situated in the Schengen area or not, Transit without Visa is NOT possible anymore for transiting in more than 1 Schengen country, because the passenger is then entering the Schengen territory (borderless). As a result, all nationals of states who require a visa for one or more Schengen states need a visa AT ALL TIMES.
Here is a list of?‚Â of Schengen visa types

Airside transit visit-ATV "Type A"This visa is required for those nationals who cannot use the Transit Without Visa-facility at all, being in direct transit in a Schengen airport when arriving, and departing from/to Non-Schengen countries.
