Michael is a super host - he personally meets you at the door and shows everything around. I didn't realize it was the case as he didn't explain it ahead of time, so there was some confusion about how to get inside.
Hosts have great welcoming personality and Michael is happy to meet new people. Has a great practical local manual printed and laminated in case this is your first time at Biarritz, which it was for me. Kitchen has some basic stuff and toiletries for the shower are offered. Mostly, caters to local French clientele vs US standards.
Location is just on the Great Beach and is super convenient to the center; the bus to the Gare/ Airport is at the entrance.
The only downside is the noise - the windows (single pane) look at a very busy street with motorcycle zooming past late after midnight. So, if you don't plan to sleep much or don't care about noise - you will be fine. Even with earplugs it was not a given for me. But this is nothing hosts can do about other than replace the windows.
No AC, so open windows in the afternoon - that does the job!
