My son's best man and his wife stayed at the Alesta last September. He booked and they took a separate flight as he works abroad. He was told it was 1,000 euros for their stay which I cannot remember was 10 days or a week.
Anyway, they only slept there and had breakfast as they kept getting taxis into Calis to be with the rest of the gang who were all staying in Calis.
At the end of their stay my son's friend went to the reception to pay 1000 Euros, only to be told he made a mistake it was 1,000 Euros each.... So the bill was 2000 Euros... A bit of a shock.
