Provided you aren’t in breach of your residential status – and who am I kidding, councils aren’t pursuing short-term rentals any more – there’s no reason why you couldn’t do that, especially if the owners Corp was prepared to rent you some desk space in your lobby.
When I say “no reason” that’s skating over the possibility that your neighbours might not want their apartment block turned into a hotel.
But there are several companies that have set up a service for Airbnb hosts so that they don’t even have to meet the grubby tourists they are inviting into our homes.
So it’s really just a moral question rather than a legal one.
