Wait for a mail with the result of your 90 days report.
Approval is not the only possible outcome. It happens frequently that people do a online notification and receive a email that it has been rejected with no reason stated, only "Please contact the nearest Immigration Office in person immediately."
No. They not look back. They ask you the most current tm30. So when you go to the immigration on lets say 4 july, you make sure you have a TM30 from the adress of your condo. Thats it.
The hotel might report you anyhow on 1 july. Then a 2th TM30 report is needed at 2 july when you will go to your own condo. Any change of adress needs to be reported.
