i dont believe there is such a place as a "lovely" place. there are places that seem lovely, but no lovely place. unless someone hacked into the game and made a new place which im not aware about.
south of hearthome city
It is in Snowpoint City.
There is no way to get an Egg in Jubilife City.
In the same place as Pokemon Diamond/Pearl
Northeast of Oreburgh City, in the building.
In both diamond and pearl the one city is Hearthome
The sixth gym is in Canalave City of Pokemon Pearl, west of Jubilife City.
You can't go to Celadon city in Pokemon Pearl. Its from an earlier region.
Between pastoria city and hearthome city.
That is the city you start at!
Its not in a city its in a tower.
Jublife city.
i think it is in jubilife city.
