While cleaning up our storage room I saw my dad's old bike collecting dust on a corner (he used to bike a lot before) so I asked him if I can have it and he said yes.

So for my question can I transform this bike into a commuter or am I better-off selling it and buying a new commuter bike? Though I really like to keep this one for some sentimental reasons rather than to sell it.
My budget is also limited, still finishing my college degree. I'll be using this going to my university and back, though I live in the city our roads/bicycle lanes here in Manila, Philippines are terrible.
