Apartment looked nice, clean and is centrally located in Palermo. However, once we got there we found four unknown devices on the walls in different areas of the apartment. The host claimed these were part of an alarm system, but it was never mentioned under the airbnb amenities section. We did not feel comfortable with having what looked like motion sensors constantly switching colors as you walked thru the apartment. We reported this issue to Airbnb and a few hours later the host suggested we could leave if we were not happy there. We immediately decided to leave and have no regrets we did, as privacy and safety are always our top priorities.
