It worked fine for my wife and daughters to quarantine in an Airbnb above Taipei Bus Station in late July. The landlord had a number of places and was quite geared up for quarantiners. I think there was someone picking the rubbish up every couple of days.
But, it was getting more difficult after their quarantine because the community stopped allowing Uber Eats and the like delivering up to the actual floor instead of the lobby. So the landlord himself was waiting there, taking food up to people for a while. Not sure how it is now.
And yes, Icon’s right that there’s no point sneaking out – many neighbours will be watching and the cellphone positioning is also quite sensitive. We heard of somebody getting an alert just because they were on their balcony (not that that’s forbidden; just that the positioning is so sensitive).
