It was an awful experience. I had booked for 2 days because i was coming from the transiberian train early in the morning (7 am) and i did not want to wait till check-in time at 2 pm. Instead of it, the girl who was working as recepcionist don't allow me to have a rest in my room because she told me that i had to pay before. I only had dollars and euros and she didn't accept them and invite me to change my money at an exchange office and pay her before coming into my room. I had to wait one and a half hour before an exchange office was open. I have never had such bad experience in my life instead of i have travelled all around the world booking many hotels per year. Normally, a hotel allow you to pay later or in any case receive foreign money as warranty.
