Overall our experience was very good, and the appartment was great in all aspects,despite minor details other people might have mentioned.
When we arrived there though there was too much noise from construction in the next building happening throughout all of the days of our stay (morning/noon/afternoon).
That wasn't communicated to us at all before the visit, we noticed it upon arrival, which is a bit wrong.
Despite that, Pau was a great host and the place was very good.
