We check in early as we took a morning flight from the states . We arrived from Frankfurt about 11am and the room was ready . If is were summer or a peak day that might have not been possible . We arranged transport by private car from the hotel which was very reasonable . . Our flight back to the states left very early in the am so I have no idea about late check out . Great hotel very accommodating as were the entire chezch people ! KDT
Check in times for most European hotels are standard. We were able to check in a little earlier: about noon because the staff was so accommodating.
Check in is no earlier than 2pm. Check out is 12.00 (midday).
Those times seems to be the normality in Europe in most hotels.
