Thanks for the review. It seems to be a very decent hotel. And the lounge seems top.
Just a remark about your drink voucher issue : Accor should really do something about it. The number of “incidents” with drink vouchers becomes really ridiculous (this is reported in so many reviews here).
And for your other issue at checkout with your pre-payment with some points, now I recommend you to check your points balance, because on my experience, they always post wrong in this situation.
