My brother lives in the Falls and works at Fallsview. He recently moved apartments and due to a delay in getting the new one he stayed at the Ritz Inn for a month.
It's a short walk to the casino (he doesn't drive, so walked daily), and
not too expensive. He did not report any bed bugs.
The room he had was dated but seemed clean enough to just crash in if all you want is a place to sleep. He said the owners were friendly.
