Rehabbing Folly Advice

[Heshel Mangel]

In middle of a rehab in Cincinnati and stuck with 2 questions. 

1) Apparently the one who measured our counter tops wasn't all quite accurate and we are left with a sink that is not centered with the windows, what would you do?

2) The ceiling had an issue that it kept cracking so the contractor filled it with the popcorn style. What is the feelings about popcorn ceilings these days? Any other suggestions how to fix the issue? 

Any advice and suggestions greatly appreciated!
