As things currently stand if your Edinburgh flat is in a block of flats, and has a shared front door and / or any communal outside space, I'm afraid that you have virtually no chance just now to obtain planning permission and then a licence to operate a new STR in Edinburgh. It is just not worth spending the time and money to even attempt it at the present time. Existing STR operators are currently operating under a grace period extension and almost all of them will also have to stop in 6 months time for this same reason.
As this will effectively pretty well then close down most of the existing short term rental accommodation in the city, future visitors to Edinburgh after September will then need to rely on the limited capacity in already overpriced hotels for their accommodation needs, and the commensurate further escalated prices that they will naturally then charge their guests as the accommodation supply and competition in the city are slashed.
Unsurprisingly large numbers of potential visitors will simply then prefer to make their travel plans to other destinations with better accommodation choice, availability and prices, rather than spend their money and bring benefit to the Edinburgh tourism and hospitality sector and to the wider Scottish economy.
Hopefully Edinburgh Council and the Scottish Government will come to their senses when they eventually see the major damage that this will cause to their tourism and hospitality industry in Edinburgh, and the inevitable destruction of the hugely important annual Edinburgh International Festival and Fringe. Perhaps then an opportunity may arise for you in the future.
Sorry not to be able to give you better news for your rental plans at this time.
