On the check in I was told that my border collie dog is too large, the reception guy was rude and only after I've made a point that there is no restriction to the size of the dog on the booking and that a small non-trained dog can do much more damage than a well traned large dog, he made 'an exeption' for me.
Please note that at the check in you will need to pay €50 deposit, which will take up to one week to get back to your bank.
If you are staying with your pet the you will need to pay €10 at the check in and be lucky if your companion dog / cat doesn't get discriminated because of their size.
