Near Onnut BTS

Hi,
I found few good condominiums near onnut bts station and it seems very convenient since there are big supermarkets. I'm going to stay with my wife and son. But my concern is i have to use train to go my university and its near Hua mak station. So i have to start from BTS, MRT and then ARL. So is it a good idea to live in sukhumvit onnut area? Does anyone know how long will it take go from onnut BTS to Hua mak ARL?

BTS On Nut to Phaya Thai about 20-25 mins
ARL Phaya Thai to Hua Mak about 10 mins

You might be better off taking a taxi or bus down Sukhumvit 71 to the ARL.

Thanks for reply. Taxi or train which will be cheaper?
