Think Fawlty Towers, and you're close.
My wife and I have just returned from a one night stay here.
As we were attending a wedding, we called the week before to ask for an early check I and I offered to pay extra for this. I was advised to call the day before and this can be confirmed. That, I did, and was told that room 1 was not booked that evening and an early check in was absolutely fine.
However, on arrival I explained that we have a room reserved and would like to check in. To which the lady on reception snorted to herself (almost breaking in to laughter) and said "I don't think so, not until 2pm". This went on for a few moments and after offering to show the call logs and even referenced the room I had been reserved she reluctantly allowed us to check in 30 minutes later.
The room, if you have seen Harry Potter, you will understand where this is going. Our room (room 1) was under a staircase. You struggled to stand in the shower room for the slope of the ceiling. When people walked up or down the stairs I could probably tell you what size shoe they were wearing! It was loud and woke us up on several occasions
The bedsheets were grubby, with what looked like moth holes in them. The towels were damp and hot water took a good 10 minutes to come through.
The curtains were grubby, the mugs had been rinsed and left wet and you guessed it, grubby.
All in all I appreciate this is an old building. It has character, however everything I have spoken about comes down to individuals. Rude welcoming, dirty sheets, damp towels.
If you would like a taste of the real life Fawlty Towers, then go and stay. You will have a great time. If you prefer a little refinement and clean rooms that aren't located under the stairs, then book else where. less
