As with all places, pros and cons!
Pros:
Great location for visiting Istanbul sites
Spacious
Excellent communication and service
Local area very trendy and has many nice cafes
Supermarkets close by
Cons:
Kitchen utensils did not appear clean
Facilities getting a bit tired and not working great
Be aware that altho there is a lift there are still steps to the apartment and also the place is on a hill, so probably not suitable to infirm or unfit people
