I love love love my yurt! We slept until noon or or took afternoon naps all week comfortably, and when the temps at night dipped, we were cozy and warm. I had two windows on opposing walls with furnace filters on them, and faced the door away from the wind so the dust didn't blow in. Even though we weren't good about keeping the door closed, it stayed pretty clean inside. I put down a large piece of canvas inside so we weren't stepping on sticky tarp and it kept the dust down inside, too. The carpet outside helped, too.
My boyfriend built the shade structure for the entry, which I just loved...gave us a place to chill with our friends and passersby, and kept the yurt cleaner and cooler. I can't imagine not having a "front porch", because like someone mentioned, the yurt isn't very inviting on it's own.
Next year I think adding a fan to circulate the air a bit will be good, it did get a little stuffy at times, but never unbearable, and MUCH better than any tent or unA/C'd RV. During the storms on Saturday and Sunday it was awesome to have a dust & wind free place to escape to. We anchored it down with rope attached to anchors taped along the roof panels (rope coming off at the joint between roof and wall) and it never budged (you can see one anchor in the picture). During the heavy winds you could see the roof panels flex a bit, but we were meticulous about making sure the tape was firmly attached when we assembled it, so it held firm all week.
