Yunus is an amazing host. He waited for us until we got to his place even though it took as longer than expected. Even in that situation he was still polite and very kind. He answered every request immediately. He also informed if anything could come up like bigger events (e.g. football games) that could affect your way to the stay..
His offered stay is exactly like on the shown pictures. The place was very clean and surrounded by a nice neighborhood.
For further stays in Istanbul I would definitely recommend Yunus as a host.
