Vildan's place is located in a central and nice area in Beyoglu which is around 10 mins walk to Taksim and 15 mins walk to Karakoy and the metro and ferry stations, the area is so active with too many shops and restaurants around , you can find whatever you want next to you , also its a quite area at night and very safe with friendly neighbors and locals.
The house is spacious with good amenities and everything you need in the kitchen and all the other rooms, the backyard is nice where you can enjoy a cup of tea with the view of the nice trees and plants, it's very cool inside the house although we stayed in July and the weather was too hot and humid outside but inside the house you don't need air conditioning , it's very safe and the area is so nice where also you can find a small park with an amazing view next to the place , also many shops and restaurants.
Vildan is too friendly and helpful, she's a perfect host who helped me and my family with many tips and recommendations and she replied quickly to my messages whenever I needed something.
We enjoyed our stay at Vildan's place and I recommend staying at her place when visiting Istanbul.
