Leo & Gretel’s place is perfect if you just need a place to crash for the night between flights. It’s close to the airport (still a 20 min walk to the main terminals or a ~7€ Uber). It’s very basic and you can tell it’s not being used as a personal residence, but it’s clean and you have a towel and a bed. Heads up that there are two other rooms that are rented out to other guests. All in all, a good place to sleep during a short layover.
