The lack of a ground sheet can be a problem on wet/soft ground. You need something on the grass to keep your sleeping bag and mat dry. I've gotten round this in the past by simply using my poncho as the ground sheet or a bivvy bag so it's not that big a deal imo.
I do most of my camping in the south now, so midges aren't as big a problem for me. However, I now bring my old gelert solo inner with me and pitch it inside the shangri-la. This gives me somewhere dry to store my stuff, and keeps insects away if needed. It takes up less than half the floorspace and gives me somewhere to sit and sleep too. I've seen an 'ooknest' or something on the internet before. This is a third-party nest which is designed to fill only half the tent but I don't know how much it is or even if it's still being sold. In midge-season, some sort of net would probably be needed.
So the tent isn't perfect. But it's a far more enjoyable experience than my other 1-person tents. I can almost stand up in it. Washing is no problem, just let the water drop onto the grass. In the winter, I sometimes use a gas lantern for heat. In the future, i plan to install a stovejack in it and make a lightweight tentstove - like a kifaru
