I'd say you'll probably be OK. By moving the fermentor, you run the risk of oxidation, which can lead to wet cardboard flavors. But, I say bottle it, and and drink it. I think (and someone with more experience may correct me) it takes awhile to set in, so if if you consume it relatively quickly, you'll be ok.
The temp is good for cellaring, but it'll take awhile longer to carb up the bottles. 3 weeks at 21 deg C is a good starting point for average gravity beers. The cooler it is, the longer it'll take to carb.
I think you'll be OK, though.
