I first stayed with Kubilay 2 years ago and had such a comfortable stay I returned this month with my daughter for her 1st Istanbul experience.
Kubilay does not live in the tourist area. His place is in a regular Turkish town where you'll experience Turkish life to enhance your stay. There is a very good bakery at the end of his road. Staff there are always helpful and it was always our first stop when going out for the day.
It's very easy to travel to Sultanahmet / Taksim / Eminonu. A couple of minutes walk from Kubilay's home is the bus station or a further walk will take you to the tram. 2 years ago I always used the tram, this time we used the buses. Both are easy
As for Kubilay's home it is extremely clean,comfortable and very welcoming.
Thank you for everything Kubilay!
