came back three weeks ago, stayed in the Pamporovo Hotel last year and I much prefer the Murgavets - its much more central, the food was fine but try to get down early as you seem to get the better food.
Ask for a room at the back as the music from the White Hart will keep you awake if you are a light sleeper, if you do get a front room, try to move before you unpack.
Swimming Pool is not very warm but the spa treatments are first class
