Radisson Blu Hotel Sheremetyevo Airport Moscow

unfortunately, we were not able to use it because nobody told us we cannot get out of the Moscow airport unless we have a visa,but luckily there's a capsule hotel in the airport where we were able to stay during our 18 hours layover. We called the Radison

hotel and told them we are cancelling because of the situation but they declined to refund our money,I think that it was your responsibilty to inform your customers about requirements on booking on foreign country like Moscow and you failed us.
