Loved it! I feel like I can't comment too much about what I was expecting compared to what I found without spoiling the surprise... I was feeling a bit awkward poking around in the rock wall with a handful of people over by the bench on the corner, but at least they had all dispersed by the time I replaced this thing.
The blacksmith's shop was great, too. We heard a lot about the history of the place and learned a bit about 'smithing, too. Yes, more chance for muggles (I generally abhor having to be "stealthy") when the place is open, but way worth it if you have a few minutes (or more, in our case) to stop in.
Here's a FP to break you into 3 digits on this one!
