A se demander si vous etes vraiment aller dans cet hotel..
Le petit dejeuner se prend en sous sol normalement.
My French is minimal. I am happy to help but need a bit more to go on. If I think what you're saying is correct. Yes we did have breakfast in the sun on the roof 3 mornings in a row. It was great - and yes I really did go to this hotel! I'm not sure where you ate but we were on the roof terrace. I can provide a receipt if you like.
