I have this tent See link. It looks like a similar design to the one you are talking about. Any experience I share is for the tent I have, and not specifically the tent you link to. I will leave it up to you to determine if the experience I have with my tent will correspond to you.

I have slept in the tent in humid summer Texas and in dry summer Utah. Also in rainy Texas and Utah. It is waterproof. However, even in dry Utah, it doesn't handle condensation very well. If you open it up all the way, there is no problem. But, when it is raining, you have to close it up and the condensation builds up pretty fast.
