My wife and I spent a night away from home at the Sterling Inn in February. We live nearby in Toronto and wanted to do something fun within a short drive from our home in Toronto. We've both been to Niagara Falls several, so this trip was just about relaxing at the hotel.
I've never stayed anywhere in the Falls before, but we wouldn't return here. The hotel felt like it was showing wear and tear, and the front desk staff were generally cold/unfriendly towards us. The breakfast delivered to our room door wasn't anything memorable. The jacuzzi tub was nice, but a lot of hotels in the Falls offer this so it's not enough of a draw to return.
There's nothing particularly wrong with this hotel, but it didn't have any "wow" factor that would entice us to come back.
