This apartment is a serviced apartment, managed by a company called Penguin Apartments. The host, I think, just represents them on Airbnb.
My advice: avoid this company, and avoid this apartment. It has metered power, which means it's just like a prepaid phone: it will cut out the moment the credit runs out.
The meter box is locked, though, so as a guest, you have no way of knowing how much power is left, and when it runs out (which it does without any notice) you have no way to fix it. You just have to wait for the property manager to come and add more credit.
I had three separate blackouts in the month I stayed here. Two times it happened were in the evening, and in both cases, it wasn't until midday the next day that they finally came to fix it, despite repeatedly telling me they'd be there "within an hour or so". That's about 18 hours, and it's more than enough time for the fridge to defrost, for your computer and phone to run out of charge, for hot water to run out etc. The apartment is totally useless in this time, and if you're in the middle of cooking dinner, as I was, too bad.
What was so frustrating, though, is that the property manager didn't seem to think this was a big deal, and didn't apologise or bother to put anything in place to ensure it didn't happen again, despite me repeatedly asking for her to make sure there was enough power to last my stay. I'm still not sure whether this was because of cheapness or incompetence.
The last time it happened the staff member who they sent to fix it even had the audacity to suggest I “use less power” as if this were some how my fault, and by using less power I would somehow extend a week's worth of power to one month's worth.
Maybe you'll be lucky and won't have any problem like that, but I definitely won't be staying with Penguin Apartments again.
