Review for Seneca Niagara Casino & Hotel Review For Seneca Niagara Casino & Hotel Google User Nov 3 '16 at 12:43 Stayed overnight on comp at Seneca Niagara. Location is perfect, rooms are wonderfully appointed and comfortable. We had an issue with the air conditioner not working. They quickly sent a very polite service technician and the issue was quickly resolved. Overall, the stay was quite pleasant and I'll definitely be returning. As long as it's comped... the cost is a bit prohibitive for locals. View full site to comment or like
