Was moving from LeoPalace to another LeoPalace mid-contract process easy?

I'm on a contract where my company may have me move to another place. I'm considering going with Leo Palace and saw you can move from one LeoPalace to another and not have to pay another Guarantor fee, etc.

Was it pretty seamless and not many hidden fee's along the way or anything? If not, I think I'll go with Leo Palace.

(Also, even when I check other websites than LeoPalace like sumo and gaijinpot, it seems like most of the apartments are Leo Palace, is it the most ubiquitous one?)

Thank you.
