A Manhattan councilman is calling on Mayor de Blasio to do more to combat illegal hotels, saying they pose a threat to tourists and neighbors alike.

In a Feb. 16 letter to the city’s Department of Information Technology, Upper East Side Councilman Ben Kallos urged the agency to provide more public information on complaints about illegal hotels and apartment owners that use sites like Airbnb and requested that 311 create a specific category for people to lodge complaints.
