I really wish I could say that I liked this hotel, but the whole experience was just plain awful. My first warning sign should have been when I made my reservation. The person I spoke with when placing my reservation had absolutely no idea what he was doing. At first he tried to book me into the wrong hotel, and then when we finally got it sorted which hotel I was actually wanting, he booked me for the wrong dates. He read me the right dates, and it was only when I called back two days later to confirm that I found out he'd given me the wrong dates. Hilton did get it fixed, but I already had a bad feeling about my stay. Then came actually staying at the hotel. The people at the check-in desk were downright rude. Then there was the room. I was supposed to be in a non-smoking room, but the room smelled strongly of cigarette smoke. The hotel staff refused to believe me, but did let me change rooms to one that didn't smell of cigarettes. However, I might as well have stayed in the first room. I was short towels, and it took four calls(over a period of 12 hours) to the front desk to get some. The sheets had not been changed, made obvious by the crumbs and fresh stains that littered them. Yes, I was able to get fresh sheets, but like the towels, it took several hours for them to be delivered. Since this is a pet friendly hotel, lucky me I got stuck in the room next to the room filled with yappy little dogs. The walls were so paper thin, all I could hear all night was barking. When I complained about it, the staff refused to believe me, and said that the walls of the room are so thick I shouldn't be able to hear anything from next door. Yeah right. I was excited to use the pool, but just like my room, it hadn't been cleaned recently. Then, I tried the fitness center. Half the equipment was broken. I tried to cut my stay short, but of course this hotel wouldn't work with me at all. They even refused to comp my stay for all the grossness I had to deal with. I will never stay with Hilton again, and I will be sure to let everyone know what a nightmare this stay was.
