Unfortunately, I had a really unpleasant experience at this accommodation. I didn't get the room I had a reservation for, but some loft, attic actually which had a bigger bed but nothing else. Since I didn't come to Pau just as a tourist for a few days, I really needed the desk where I could work, but this room didn't have it. I couldn't close the room doors because the lock was broken. Some bigger closet was also not there and you would need it if you are supposed to be there for a month (my room was supposed to have one). There was some small one and it was full of things. Toilet itself was 2 floors below this attick, and the bathroom with the shower cabins one floor below.
I got to the address pretty late first evening (one of the positive points that you can do it here) and when I asked the lady about my room she got angry and didn't want to discuss and told me we would talk the next day. However, when I wanted to talk she didn't have time and told me to talk to her husband. None of them actually told me why I didn't get the room I reserved, no explanation or apology, they even didn't want to hear me out and I still don't know if that room even exists (although I think someone else was given that room) but I decided to leave after 2 days. There were some problems with changing the reservation, but it turned up to be some airbnb bug so I can at least thank the hosts for not making some big issues with that and consequently with returning the money for the rest of the staying, although they confirmed my request for changing the reservation only at the end of 24h deadline (but it could be it was really when they saw it).
Altogether, this might be nice for someone staying there for 2-3 days, who wil only use the room for sleeping and so on. Old wood furniture has some charm then and it is kind of special but with all the disadvantages this is not a comfortable and practical accommodation for longer periods. Above that, I was completely disappointed by the attitude of the hosts so I wouldn't recommend booking in here.
