Cocckroach infestation

Worst experience ever. Stayed there for a weekend and the flat was infested with ****roaches. 100s of then walking on us even while we slept. In the bathrooms , bedrooms and kitchen. It was horrific we never slept at all. We had notified reception who advised that the manager will contact us however it's 2 weeks later and nobody got back to me. I have all the videos as proof
