We spent two nights in Palermo and stayed at Giovanni’s place. While the location was great (located centrally but not loud at night) and comes with air conditioning, the odour in the apartment was akin to that of sewage. We could tell the air was stale (understandable in older Italian homes) when we walked in but the sewage smell was something different and incredibly off putting. It was not as strong in the bedroom so sleeping at night was not as uncomfortable.
