Whilst the Grand Heritage hotel in Perast is beautiful architecturally, situated in a perfect location in a very pretty town, with the exceptionally friendly and professional staff, a major issue exists with its sanitation system. So much so, it completely spoilt our holiday! A constant strong stench of raw sewage hovered over every waterside hotel, restaurant, bar, terrace and beach. There was no warning of this issue anywhere, so when we initially arrived we swam in the sea directly in front of our hotel and a couple of days later, all of my family ended up bed ridden with sickness and diarrhea for a few days. It completely ruined our holiday. We paid a considerable price for this 5* hotel, I would strongly advise people to consider this problem prior to booking. We spoke to a lot of guests during our stay and the same topic kept arising. Considering this area has been listed as a World Heritage destination, the sewage is damaging and dangerous to both humans and wildlife alike. This hazard needs to be addressed ASAP and funding needs to be implemented by both hotels and Government bodies. It’s an huge environmental health hazard. Saying that, the hotel inside was spotless and our the cleaning staff were amazing. Food was mediocre, not a true reflection of a 5* hotel. As a family we have travelled extensively and have stayed in some amazing locations and resorts, in our view this place could be ‘amazing’ if the sewerage issue could be addressed!
