Everything was perfect!
The best location in Istanbul, close to public transportation, amazing neighborhood and very comfortable. Has aircon which is a rarity in Istanbul. And the most important, the host. Once we lost the keys inside and he quickly sent us the locksmith and again we took one of the keys with us by mistake when we were leaving for the airport but he didnt charge us for the key.He even let us to do a late checkout.
I definitely recommend this flat. The flat itself is awesome and the host made our stay stress-free.
Thanks again!
