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.

A great Lego set
This Lego set is very intricate and fun to put together. It looks great when completed. There were no Lego pieces missing.

Fantastic LEGO set!
As an AFOL, these are the only sets I purchase. I've collected all but 2 of this wonderful series. (I'd love to get my hands on a decently priced Green Grocer or Market Street.) This set kept me busy for the better part of 2 days and the details are amazing! There's a bakery, florist, coffee shop, music shop, ballet studio, photography studio, dentist's office, and a studio apartment. The only thing I was most displeased with was the condition of the LEGO box. It was opened at both ends, had a bright green sticker on the front and looked like it had been beat up pretty bad. As someone who keeps the boxes in pristine condition, this was a major disappointment for me. Luckily all pieces/parts were there. I absolutely love this set, regardless of the crappy box I got it in.

Wish I could give this build more than 5 stars !! ⭐️
This set was a great challenge. With a little over 4,000 pieces I underestimated how detailed this build would be. After 14ish hours put in it’s worth the challenge. Would highly recommend to Lego Lovers (added the Bookstore once done & it really puts it all together). Included pictures of some lil details that were added in :)

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.

Loved it, was a super fun build, and I can't wait to purchase another 4000+ piece set in the near future. Definitely recommend for any avid LEGO builders, you won't be disappointed.

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.
