"It is a fun set to build. Not too complex so can definitely be assembled with children and let them do it all. It is quite sturdy, which matters as the fun comes with opening it up. Very nice touch to put one customer as a disabled person. All characters are "yellow" so one could argue another colour could have been added but it is already a good step for diversity in your lego village...
The house looks great, the colour works well. I really love the organ, such a lovely piece of lego engineering! You get a haunted painting too which comes with its own battery so no need to purchase that one separately.
There is a lot of interesting details, most of them setting you a few years back. If you have been a lego "player" for many years, you may recognise some of the artefacts included. I love that there are also 2 Freestanding ghosts. The front garden is cute with the tombstone and the pumpkin. Nice touch.
Finally, I think it is quite easy to make this set modular if you wish to install it in your lego city. I would put it not too far from the Ghostbuster's HQ though, just to keep it all under control..."
