We had a very pleasant and quiet time in Üsküdar at Başak's. Everything was nice and tidy, she lives with two beautiful and friendly cats. Special mention to how beautiful the apartment is kept by her.
The location is far enough from the tourist areas of Istanbul to have a relaxing time away from the hustle but close enough to get there on a short ferry trip plus walking through amazing scenery.
Nice, cozy restaurants withing walking distance and a beautiful park across the street with astonishing views of Istanbul.
