I can imagine that this place must look great in summer. I recommend to go for a commented tour with some of the ladies working at the place. No need to book anything, just wait for the tour to start when you get to the museum. With explanation of how the things worked back then and with some background stories, the visit is much more interesting than just looking around.
Most of the tour or walk will happen outside, but some of the houses are open and you can peak in.
Since the place has various opening hours during different months, check this information in advance. The tickets can be purchases at the place. It's possible to pay with a card, but the payment terminal is not always catching signal, so there might be a problem with that, we were told.
