This is an artistic & comfortable place. Friendly English speaking receptionists; one girl was happy to tell me all the great places to visit in Kaliningrad. Beautiful design. Also very practical; dorm beds have curtains for privacy, a socket for charging, a reading light & a shelf. Also a large lockable drawer with key, for valuables.
It's about 20 mins walk from central spots, Kant Island or Victory Sq. There's a Spar supermarket in a street behind it, a few minutes a walk. The maritime museum, complete with Soviet submarine, is just outside.
To reach Victory Sq; turn right from the hostel, take the first right, cross the road at the bus stop, & follow the narrow road on the left. Lovely tree-lined walk, which passes some beautiful old city gates & a Soviet war memorial. This memorial is a mass grave for 120,000 soldiers who died taking Kaliningrad in WWII. It has an eternal flame; & the atmosphere is very peaceful.
