Mark is an exceptional host. I reached the bnb after a late flight and Mark was already at the place waiting for me for a super quick and painless check-in experience. He's extremely responsive and reachable and gives you detailed repsonses to any questions you may have. The apartment is nice and cozy, and the standard of cleanliness is outstanding. I had a small issue with the boiler, but Mark literally got it fixed at short notice as soon as I told him about it, and that just shows that he truly cares for his guests and makes all effort to make your stay perfect. If you want to rent a bnb at one of Istanbul's most peaceful areas yet very close to the hustle of their culture, Mark's place is what you're looking for.
