Passage Du Gois

It's actually a nice place to stay as the weather is warm during summer, and there is almost no one there in winter (no humans, no cars or humans' noise, it's both creepy and amazing at the same time). They have beer, good food, and people are usually nice. They also have some kind of local "HOA" (or laws maybe?) across the island which explains why most houses stayed in their traditional old-school style (blue shutters, white walls, specific chimneys that are sometimes fake...)
Feel free to ask anything. It's the kind of place I would live in if I could be full-remote.
Edit 1: While this post may be off-topic, I remember that there was a retro-gaming shop that used to sell NES, Super NES, Neo Geo, and Japanese games. It closed a few years ago but it was very strange seeing that on an island mostly populated by old people. That was not the kind of shop you would expect here.
The town definitely has rules about how your home must look (if it's a new construction). Old houses don't though.
The town definitely empties out during the colder months but my wife and I still enjoy going there because it beats city living. Also they installed fiber optic internet not too long ago. Since we WFH, we try to go there as often as possible.
The chimneys are likely real but sealed because of climate change related rules.
There's also a castle that dates back to the 12th century built to protect monks from vikings. They've recently finished some restoration work there too.
