I rarely leave negative reviews, but this hotel deserves one.
The day before our stay, we discovered that reception/check-in closes early. I admit I missed this when booking, but we arrived at 11:15 PM, while Hotels.com stated check-in was available until 11:30 PM. The door was locked, and when a staff member finally came out, he was immediately rude and told us they had closed at 11 PM. He eventually let us in, but then demanded a £25 cash deposit for the room key. This was never mentioned anywhere. Since we had no cash, he kept my passport until we could withdraw money the next day.
The room was basic, which is expected for the price, but the bathroom had a completely clear window facing the hallway, meaning anyone outside could see in. That is completely unacceptable.
Other issues included no soap, a very hard mattress, dirty and worn facilities, clipped fingernails left on the floor, and extremely poor soundproofing.
Cheap accommodation comes with lower expectations, and that's fine. But rude staff, hidden requirements, and a complete lack of privacy are not acceptable.
