Hotel is very clean. Roomy. Friendly staff. Great breakfast. Unfortunately, room was stinky. I wish I would’ve brought a candle. Not sure if it was pipes. I’ve been here a few times and it was a great experience. Also, the frig wasn’t clean. Maybe the housekeeper forgot but that happens. As we were trying to sleep in, we can hear the house keepers talking loudly to each other in the hallway as they were cleaning. I thought that was unnecessary. Especially being a hotel. But all in all, we enjoyed our stay.
