What are Beşiktaş Furnished Rental Price Levels?

Furnished rental is one of my focus real estate areas.
I rent out well-maintained middle and upper segment flats, residences and villas furnished by offering them to my local and international marketing channels.
Beşiktaş and the Bosphorus line are the regions where I primarily work.
During the week, I did my expert work on a well-maintained flat with a view in the Ulus area.
In general, the m² rental price of furnished flats varies between 30% and 50% compared to unfurnished flats.
In general, the unfurnished m² rental price in old buildings in the Ulus region varies between 350 TL and 400 TL.
In the Gayrettepe region, the rental price per m² in furnished old buildings varies between 275 TL and 350 TL.
An important advantage of the Beşiktaş region in furnished rentals is that it is an attractive location for many international people.
