Paris Opatija in Opatija

This was the worst hotel out of more than 50 hotels we’ve stayed in across 30 countries. We have genuinely never experienced anything worse. We honestly don’t understand how this hotel has a 4-star rating.
The entire hotel smells overwhelmingly of cigarettes and ashtrays. Yes, there is a casino, and people smoke everywhere, but the smell spreads throughout the whole building. Our room was on the 6th floor, yet it still reeked of smoke. Even the bed sheets and towels smelled like cigarettes.
The room itself was extremely dirty - there were hairs in the towels, clogged hair in the bathroom drain, and large stains on the carpet. The smoke detector on the ceiling was literally covered with a piece of medical bandage, already yellow from age, which is both shocking and unsafe.
We checked in at midnight and couldn’t even stay there. We left the room after 20 minutes and moved to another hotel 5 minutes away.
Do not be misled by the photos or reviews. If you read carefully, you’ll see that guests mention being asked by the hotel to leave a 10/10 review in exchange for a refund. That says everything.
When we left in the middle of the night, the concierge pretended not to understand what we were talking about regarding the cigarette smell - which is ridiculous. Of course, if you sit in that environment all day, you probably stop noticing it.
They canceled our booking after we left, but did not issue a refund - most likely to prevent us from leaving a negative review. Fortunately, Booking still allows us to share our experience.
If you have any self-respect, do not stay here under any circumstances. If you’re nearby, just walk in for a minute - you’ll immediately understand everything.
