Mr. Suleyman is a very kind host who communicates with the guests in a timely manner and provides every assistance he can. The apartment was clean and spacious for a studio apartment and two extra couch/sofas made it a comfortable stay for our company of three. The clean bedding sheets and towels were abundant and having a washing machine made it a comfortable stay. Washing detergents and grocery can be purchased from the small supermarket in front of the building. The apartment had a very good interior heating that accommodated us well during the rainy week of our vacation.
The streets in the vicinity of apartment, like almost everywhere else in Besiktas, have steep slopes so I'd recommend using taxi apps (bitaxi, uber) to reach the place if you are in a hurry or are carrying heavy luggage.
