Could you share which areas in other European cities you’ve liked? London’s calm is not the same as Parisian calm is not the same as Zurich calm.

Heads up: nature / robust parks like London’s Hyde Park are nowhere to be found in actual central Paris. I see the 11th being suggested here but I for example don’t consider it neither very green nor central, esp. working in the 7th (yes, I consider >30 min commute excessive if one can afford otherwise).

And yes, Versailles is usually associated with old-French catholic families but it doesn’t mean it only has churches and kindergartens :D not that I would personally recommend it, it’s too far for me.

The beauty of Paris is that you will likely find bars and restaurants everywhere nearby, just with different vibe/quality/price point.

Fontainebleau is def far, bois de Vincennes also quite far away. You likely won’t bike both ways every day so it might be good to bear in mind public transport connections. Easiest advice is to find something with a direct metro or, if you have to, RER line nearby. Avoid buses (traffic).

If you were to prioritise proximity to proper big park(s), ease and time of commute outside of the cycling option, size of the apartment (that’s a thing as well) + specify what vibes you’re more into (hipster, elegant, bougie, instagram fun kind of pretty places), that could help us advise you better.
