Where to relocate in Osaka?

I currently live in Hyogo prefecture and work in Osaka, Toyonaka and I am looking to move to be closer to work but also to be closer to Osaka in general. I am looking for a location that has easy/convenient access to Umeda/Namba etc so I can go visit sometimes. Also an area to live that has restaurants, gyms, all those fun things nearby lol or again with easy access to. I don't have a car so my only mode of transport would be a bicycle.

In terms of rent and size, preferably 1DK or 1LDK and not too expensive. Where I live is fine but the rent is very high for a 1K, almost 80,000 a month! So if I can get cheaper, that would be great!

Thanks!!
