I live not too far from Seminyak which is popular destination. Lots of cheap (local warung) or fancy restaurant around. You can walk or hire a motorbike (IDR 70k per day).
I live alone and work from 3.30pm-8.30pm everyday. I was a couchsurfing host in Jakarta but now in bali the rent cost me half of my salary so airbnb would be the best option for me atm.
