Ayda was very welcoming and helpful through our entire vacation. It was easy to reach and communicate with her at all times. Her apartment is comfortable and very well equipped as mentioned in the descriptions. It's a new and secure building in a central neighborhood which is pretty quiet compared to other central areas of Istanbul. There is a small supermarket and a bus station very close to the apartment which makes it easy to travel in the city. You can also just walk to the center of Beşiktaş in 5 minutes.
