I got the Trevi Fountain as a birthday present from my friends, who embrace my newly found LEGO enthusiasm. Such a cool present, such super cool friends! I love the model, it's my first from the Architecture series. It was fun to build - intricate details combined with some lovely technics and in the end a wonderful interpretation of the actual fountain. The instruction book has a grown-up wibe with the sleek black pages, info of the building, and the words from the LEGO designer. The toughest part to build might be the water. One has to be careful, and I would imagine that if you are a more short-tempered LEGO builder, the brick separator included will come in handy. A nice touch is that the instruction book has red markings to make the building of the water easier. The finished building is very very beautiful. I personally don't mind the clear blue bricks of the wall element being behind the transparent ones at all, because I really like how the fountain looks so different in different lights - just like the actual Trevi Fountain. But I can imagine some people might find this troubling. I always imagine what it would be like as a child to receive the LEGO models I build. The thing is, this model has 12+ age recommendation, but if I would have gotten this when I was 9 or older, I would have been so excited! So if you have a child who loves to build things, enjoys beautiful sceneries, and loves to draw houses and design apartment lay-outs, and is good with puzzles, this is a perfect present for them. And same goes with grown-ups! :D
