First of all Yusuf is a great host. Every little remark or wish we had, he immediately helped us. He is very helpful and thoughtful.
Everything you need is reachable by foot. Three supermarkets in walking distance, a bakery and plenty of little restaurants. The Taksim-Square is 15min by foot and from there you can start your day easily. Every Sunday there is a big market right at the apartment which offers basically everything. All in all a great experience and worth the money.
