Jen, our guide was pretty great, told some good stories and was super friendly but the size of this tour (more than 20) made for a not so "spooky" experience. Some were locals and many were tourists, some were loud (and probably drunk.) We did the 11pm tour and it was a beautiful way to see the city by night. I would say if you want to have a knowledgeable guide take you on an easy walking tour of the city, check it out. If you want to be scared or possibly experience something creepy, then this large group isn't going to satisfy that. Wear comfy shoes, of course, the streets and paths are old!
