Everything in the description, the pictures, and location for Kaan's place is accurate. Kaan's representative Nalan met us at the door when we arrived and showed us around the apartment. Which we appreciated. Please note the streets in the area have a significant decline (downhill) when walking to the apartment from Taksim and you have to climb back up hill when you are going to Taksim to catch the metro.
The Havaist airport bus stop is on the opposite side of Taksim Square from the apartment. Walkable with your luggage from the bus stop to the apartment.
If you are looking for a place near Taksim and everything it has to offer, Kaan's place is worth booking for your stay. Thank you Kaan and Nalan for hosting us.
