Classify the given hotel review based on the sentiment it expresses into two classes: negative and positive.
Q: Grant it, this hotel seems very nice, but I was not at all pleased with my stay here. The customer service was horrible. I had to request more towels and washcloths several times before receiving them and my linen had not been replaced either. For as much as I paid to stay here, you'd think the least you'd get is an iron. Not! I had to request an iron, too! In addition to all of the failed amenities, I was mistakenly charged twice for my stay and wasn't reimbursed until an entire week later. The next time I choose to visit Chicago, Swissotel will be the last place I think to stay.

A:
negative
