This place was a great place to stay. It is completely like the photos that you see in the website. The amenities are complete and clean and of good quality. If there is anything missing Adem and his assistant are alway available to prepare everything as soon as possible. They are really responsible and you can trust in what they say. Adem's English is well enough to talk to foreign travellers.
Also the location is perfect. In Rumeli Street near Osmanbey Metro Station, 5 minutes walking mostly flat, and while you are walking this path you are amused with lots of shops and beautiful cafe's. Also 2 big markets for daily needs are 8 or 9 minutes away. The location is great for tourists who wants to go around in Istanbul and wants to have a relax stay in the house.
Mostly recommended.
