I visited 5 of 6 locations soon after the inscription some 10 years ago, but still have not managed to see the most appreciated component by our communitity - Tuschkastensiedlung. The first visit I would call as "exploratory", and I was not disappoined. My favorit component is Hufeisensiedlung and I visited this place then several times on every occasion. The reason is not only convenient location on the U-bahn line but very delicate atmosphere I feel during every my visit.

I like not only the blueish horshoe building with the pond in the middle but also dark red small buildings assembled to rhombus shapes located to the West from the main building. 

I was thinking intensively why I tend to visit the Hufeisen, and my answer is that I do not take this site as an intelectual construct that was evident from other reviews - that the site is interesting because of permanent impact on few prominent Bauhaus architects on our everyday life. Instead, I take it in purely emotional way based on what I can see on the site but not what I have read about modern architecture before. In fact, I usualy (but not always) use this principle also during my visitits to medieval sites. To conclude, parts of this WHS emanate similar spirit to me as I can feel for example in Siena. This justifies its OUV in my opinion (I hope it is not too esoteric  - see PHOTO).
