>Virbank is the best
>City but small and dim enough to be comfy
>Gets snowy in the winter
>comfy as fuck music
>Rewarded for revisiting due to the Surf area
>Despite being "dirty" like you're in the bad part of town, all the people there are surprisingly chill
>Including Roxie, the bestest, cutest PokéGirl EVER!
And as a bonus, It's got PokéWood just to the north, where you can get to see a more glamorous side of the area, get rich and famous, and set yourself up with Items for the rest of the game. Virbank definitely is one of my favorite places to be in the games.
Honorable Mentions;
>Goldenrod
I always imagined Goldenrod as the London of Pokémon. Pretty sure the anime gave it double-decker red buses, which helped.
>Ecruteak
Speaks for itself, comfy autumn-set Japanese style town.
>Laverre
I wish they gave you more reason to stay here longer, or return in some side-quest(s). Very comfy town, preceded by a swamp. Underrated.
>That one route in Hoenn with the Secret Base by the Waterfall, and the Weather Institute at the end;
Hoenn is notoriously un-comfy, with the loud constant trumpets, endless Wingulls and water, and harsher adventurous environments. But this one route I think is possibly the most enjoyable to explore in the entire franchise.
>Snowpoint
The biggest sigh of relief to reach this comfy town after making it through the Mountain, and the blizzard. The only problem with this town is such little happens here because Regigigas is basically permalocked now. I would like to think there will be more (possibly post-game) to do here in a remake.
