Great location (next to Taksim square) and communication with Wassim was easy. The flat is spacious. It could be curated a bit more, but you have everything you need for a good staying in Istanbul. Please note that the flat is in a very hilly part of town; we were with our parents (in their 70s) and they struggled a bit when we were coming back home climbing up the surrounding steep streets or stairs. But for younger couples/families, the flat is in a great location to visit all the town. A couple of evenings, we even took takeaway food from the restaurants near Taksim square and ate at home. It was very convenient and easy. Also, the flat is within walking distance from Changir, a great area full of nice caffes and little bars. I would strongly suggest a visit for a chilled-out evening.
