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.

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

Loves This Huge Legos
Girlfriend loves these Legos now... Gives her stuff to do now that we're retired. This one will be a "beast". She just started it, so she's busy and happy.... Until she gets frustrated! Happy camper. 😀

Assembly square
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.

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.

Another Amazing creator Expert Set
4000+ pieces for less than 10 cents a piece is a great price. The 16+ age category did not deter my 9 year old from putting it together, spending about 4 hours a day for about 5 days to assemble. The parts stay together well, and he plays with it like a house, separating the floors (As it is designed to do) to play with the mini-figures as if they are dolls in a doll house. It is an amazing set, and now seems to be on the Lego Shop's Hard to Find list.

Fantastic lego product
This is by far one of the best sets from lego. The modular buildings have always been excellent, but this one is the biggest of them and a great mix of the best elements. Certainly not a quick build by any means, but a fun build, and very satisfying once done.
