Not exactly a hotel, but we booked a house in the west of Ireland at the height of the boom, when everybody was moving into new bungalows and renting the old houses to the English. When we got there we found a nice mound of steaming peat outside, original (not replica) brass beds, etc etc. The best bits were a shower draining into a hole in the ground, and an old fridge which had been sprayed with green metalflake car paint to resemble a Smeg (not). Said fridge's door was held shut by a brick. Nice week there though, the kids loved it!

Then there was RAF cadet camp at Binbrook - alarm clock was Lightnings taking off on reheat!

In the seventies, many friends stayed at the immortal Pensao Borges in Regua, north Portugal. See excellent shot, probably from one of the bedroom windows!

I have seen some interior shots - nothing seemed to have changed since about 1925. The wallpaper hung off in strips - the sink and shower were fed by a tank above the bathroom window which was in turn fed by the roof gutters. A rope was pulled to release the flow.

Which reminds me, I think I have been given the photos concerned, must have a ferret about!
