Actually a trip to Paris nearly sent me over the edge too and I have been there loads of time..
My daughter was spending a year there as part of her University course and lived in a lovely foyer in the suburbs. I asked her to book me a room locally and requested that she booked somewhere that was not too expensive as we all coming.
After a VERY stressful journey we arrived late, hungry and exhausted. It was dark and we found the hotel which was the worst place I have ever stayed. We climbed up several rickity stairs to like an attic room.
The beds were so old you fell in the middle, there was mildrew in the bathroom, the light fittings were cracked and when the RER went by the whole room shook. We tried to find somewhere else but the nearest hotels were full.
We had to stay as there was nothing we could do.
In the middle of the night the scratching started
The following night was in 4 star luxury
I have never spent such a terrifying night...
