My stay at Elf Hostel was perfect!
Great service, there is always somebody available to help you with anything you need. They helped me with local tips, provided me a towel because I didn't take one, let me borrow the iron.
The place is super clean, there is somebody cleaning the bathroom all day long.
Great people stay here and eventhoe it's not in the center the bus stop is right in front.
If I go to Prague again, I am definitely staying here!!
100% recommended!
