Got this tent last year and have been so pleased with it. It is well built and roomy. The metal poles make it a heavy tent to carry but gives it such a robust feel, and I have no concerns about sleeping in it during bad weather. First time I took it out we got caught in a heavy thunder storm and we managed to fit the large group we were camping with (+20 people - kids and adults) in the tent, and absolutly no leaks. I was amazed! Not that I'd necessarily recommend that many people in it at a time, but just to give you an idea of how roomy it is.
Like the one of the previous reviewers, I use two of the rooms to sleep in and the third as storage, just to keep things out of site. The windows and the colour of the tent mean that it's nice and bright inside. I have not found it drafty, in fact I like the ventilation, I think it's important to have good ventilation in a tent, especially if you have to spend a long time in it.
I agree with the other reviewers in that the tent instructions can be a bit confusing first time, but so simple to put up second time round. A practice run in the garden (if you can fit it in) would be a good idea.
I'm glad I got this tent after a lot of time looking round at other tents. I got this tent because I wanted to be able to camp with two kids and have enough room to be comfortable in bad weather, and that would last us a good few years. This ticks all the boxes.
