    • One of the Best Modulars ever.
What an amazing set! So many details. I won't spoil the surprises, but it is a great build! Sitting on one and a half base plates, it dominates any city street. I love the little nods to previous modular sets. I've had it now for 6 years and still love looking at it.

    • Great set of Legos
I ordered this set knowing I was overpaying but that was on me. But when I got it it was in pristine condition and ready to be put together. It was something I had wanted to go along with my other buildings. It was not easy to assemble since it was expert but it was fun to assemble. So I would say this is an adult piece not for the younger crowd, that is what i mean by not easy.I love it and can't wait to start putting it together, so I can not account for it having all its pieces but I am assuming it does. Lego's rocks. But I did not get this from the lego company, I got it from an online seller who was swift in shipping, had a great product, although a steep price. :) But those willing to pay , well its on us, right. ... show more

    • Fun build
Overall this is a fun build with good minifigs and interesting building experience. Pros: 1. Large and deep build with lots of pieces. 2. Good minifigs (with classic standard grin heads). 3. Lots of details for various rooms, especially the room with lego micro builds. 4. No sticker, all printed bricks (modular rocks) 5. Good display & play set Minor cons: 1. The top floor kitchen area of the middle building is not covered, it would be nice if that area is covered. 2. More expensive than other modular buildings (but bigger) 3. One missing piece, but easily get it shipped from lego.com ... show more

I love the way this lego set looks. It has so many intricate details. It is just amazing when looking at it. It is definitely a more advanced build. You would have to open up several bags per section and dig through a giant pile of pieces. There was a lot of pieces to put together on many of the steps. This would be a perfect project to keep a whole family busy because it would give each member plenty of pieces to put together. ... show more

    • Expert Level - Looks Amazing with Lights
For those who are an expert Lego builder, this is a great purchase. We've added this to our collection and purchased a lighting kit (not Lego) for it. It really brings out all of the details that Lego has.
