I will be in Kiev next month for only 3 days and would like to know if anybody out there knows the best reliable way to book a hotel in advance.I would like to stay at the Hotel Rus so I went to their web site and put in the days I would be there and it told me there were no rooms available.So I went to another hotel booking web site and requested the same days and hotel and it told their were rooms available. Any help would be appreciated
