Overall this is a decent appartment, located in a very nice area of Biarritz. Fanny was very helpful to adapt to our arrival and departure times during check-in and check-out.
The biggest negative point was undoubtedly the fact that they have a very small individual hot water tank, which only allows to take a shower to ONE person (and during no more than 5 or 6 minutes). Meaning, if you're a couple, the second person will have to wait several hours until the hot water is back.
Other cheap details like not providing with toilet paper, garbage bags, laundry detergent (I understand this is not a 1st need product, but if you're at the appartment for a few days and you want to quickly use the laundry machine, you're "forced" to buy a whole detergent just for a single use...), etc and the fact that we then discovered several other available bigger appartments in the same/similar location for a much lower price, were some of the reasons that didn't make me give a 5 starts to this appartment.
