If everything goes well at Sentral and you receive a good room and have no issues, I'm sure it could be fine.
This did not happen to us, and so started the Kafkaesque journey into hell. They did not give us an acceptable room (the bedroom did not have 4 walls which is...kind of a requirement for it to be a bedroom). We contacted Sentral. They responded promptly to tell us they were forwarding our request to the "relevant departments". Who are those? Who knows. Its bureaucratic gibberish to keep their response time on AirBNB up without actually addressing our issue. If theres a problem do we address the front desk or AirBNB? Who knows, it seems that they were in communication but told different things at different times.
That being said, they did, eventually, respond to us and offer us a separate room. At that point our stay was halfway over and we had made do with what we had.
I believe the only reason our issues is because one of the individuals at the front desk was actually pretty competent and helpful. If not for her, our stay would have been quite unmanageable.
I think the most important things to realize about Sentral is that you are NOT getting the room you booked. Instead it is a "similar" room which can be....not really that similar.
