Hotel Novum Garden Side

Hi, next week (from 19. August) I will be spending some holidays at your nice hotel and would like to know; is there a possibility to do a PCR(Corona)-Test directly or near close to the Hotel before I return to Germany? I just got an email about the latest Corona virus update that says I must be tested before returning to Germany, but I don't how long does the test would actually take if I do it directly at the airport and I don't want to be 5 hours at the airport before taking my flight. Thanks in advance
