Smell of cigarettes
We had booked a nonsmoking room, and after not the best reception from the guy running the bar, we found our room. Sadly, we were met with an overwhelming smell of stale cigarettes and nicotene. The room was also very cramped. I could see my wife was quite upset about it all, so we asked for a refund and left. The landlady, to give her credit, was quite apologetic and offered us a part refund which we accepted.
