Full bull shit, we have not any problems with enters in the Hotel prostitutes. Firstly, the Ukrainian hotels have lost a lot of its guests and all staff turn a blind eye to such "visitors". They understand the need to do everything to make you satisfied and coming back in the next your trip to the their Hotel. Except only a few Hotel: Hotel Rus, Ukraine and Kozatskiy. I know this will solve the problem 200 UAH (10-20$).
