I've never been involved with the GS but found this to be an interesting house and enjoyed learning about J. Low. This is a worthwhile place to visit. However, like some other reviewers, I did feel a little bit rushed, and the guide seemed a bit tired. This is understandable given the numbers of visitors, especially this year, but it is unfortunate. My recommendation would be to see the house in the morning, perhaps just after it opens, when things may be less busy.
