Márton Áron hostel

I'm trying to get in touch with the guys at Márton Áron Hostel but I'm having no luck. One room has already been booked and a second one needs to be booked (Actually a shift from 3 people 1 room to 2, 2 person rooms)

Anyone on the forum know how to get in touch with these folks other than using their contact form on their website (which seems to go into a blackhole)?
