Kalen is by far the best air bnb host I have ever been hosted by. A genuinely kind and helpful person - he took us on a walking tour of the area on the first day and showed us some of the best eating spots.
He also helped us out when we were unable to travel due to severe weather conditions and continued to give us recommendations even when we were no longer staying at his place.
The place was also lovely, exactly as described and in a central part of Istanbul. Very good value for money.
I could not recommend Kalen and his place more. Big thank you.
