I stayed at Ulli's place for a month. It was one of the best experiences I've had this year. She was such a lovely host! Her place is just as beautiful as reflected in the photos, and on the top of that, with her positive energy filling up the apartment, it becomes your peaceful escape in Istanbul. I feel so fortunate to know her. I enjoyed every day I spent there. Moda is a great neighbourhood, from the apartment it is easy to go to anywhere in Istanbul (with boat, subway). Her place is in the heart of the Kadikoy, where you can find cool bars, restaurants and coffee shops walking distance and still can enjoy a quite night sleep after a long day.
I highly recommend Ulli's place to everyone who wants to have a real Istanbul experience :)
