Yes, it is a funny old slightly ramshackle hotel which could be magnificent but isn't. Best Western would have to spend a fortune to bring it properly up to date and I doubt they'd get a return on it for centuries! However, after being in a mousehole in Biarritz for 3 days, we loved it. Huge room, sofa, chairs at one end, high ceilings, decent bed (far better than BW Biarritz) big, strangely open to the room, bathroom with a weird shower arrangement but no worries, Nespresso machine (all good!) with the only real downside being the inefficient floor standing air con unit in the corner which roared like a dinosaur. You couldn't possibly sleep with it on overnight, hence we woke at 3am in an overheated mess! We cranked the windows open and coped with just the cool night air. We didn't eat in the hotel so can't comment on the food.
Trying to locate the place is tricky as it's buried in the middle of no-entry streets and the parking is underneath another building 50 yards away. The entrance is tight but doable even in our big X3 and it's free!
You can see the former grandeur of the place in the public areas and it's quirky and interesting but tired. Nevertheless, location is fab, parking close and the price is ok. We would stay here again and we aren't easy to please! .....oh...and Pau is beautiful! less
