Done this quest couple of weeks ago personally I found the vampire guy the hardest to kill had 3 attempts: 1st:ran out of food and had to run away, 2nd: Again ran out of food and surived with 1 hp :ohnoes: 3rd: sucesfully killed him with no food left and 4 hp left. Overall the quest wasnt hard but it surely was scary, I think that long and scary quests are the best, they really take you into the lore of the game.
