We stayed there last year and had a great time, booked again for 24 February. Its up a short hill from the Mourgavets, so its a little quieter and the less impersonal than some of the more expensive hotels. Food simple...but its good and plentiful...great bar area with a log fire to relax by.
Theres a few pics of the Prespa from last years holiday here!
