I would trust Jakub with your travel plans!
We actually didn't stay in this specific apartment but Jakub informed us of the change immediately and put us in an even better place near old town square (puskin apartments). The area near old town is a little noisy but not bad if you keep the windows shut.
Jakub js super quick when replying to emails and will accommodate your needs. He called a taxi to pick us up from and to the airport which was very helpful. Also, we were able to leave our luggage at the reception area since we wanted a later check out time. Overall, great experience. Thanks!
