Ege's apartment was a great experience, located in the posh area of Bostanci, near to Bagdat Caddesi away from the crowded areas of the European side, I highly recommend Ege's apartment. It is located in a high floor so you can enjoy the beautiful view of the Princes islands and Asia Minor (even snow covered Uludag) when the atmosphere is clear. The apartment is very modern, well designed in a brand new safe building, it's fully equipped and sparkling clean! Transportation is very easy, the Bostanci Marmaray Station is within 10 min walking distance and the it takes 12 minutes to reach Bostanci port where you can easily reach the islands (Heybeliada is a must). The Marmaray train will take you within 30 .. to 40 min to the heart of Istanbul's old city.
Everything was very comfortable at Ege's apartment. Ege & Serkan are great people, very polite and helpful, I am looking forward to meeting them again soon!
