I recently finished running this module as a Play by Post campaign. Both me and my players found it highly entertaining.
The adventure has a good mix of roleplay and combat, with interesting NPCs and challenging fights. Neil Spicer does a terrific job of building up tension, while still including opportunities for comic relief.
The module does benefit from some adaptation, and as such I would not recommend it for an inexperienced GM. For anyone running the module, I strongly suggest listening to the Pathfinder Chronicles podcast and visiting the podcast forum for extra materials, as well as using the extra material provided in the paizo blog. Implementing the suggested changes from the blog and podcast goes a long way towards meeting the main critiques of the module, namely the lack of variation in enemies and the potential lethality of the final fight.
