What Serdar lacks in organisation, he does make up for in being very friendly and helpful. The apartment is pleasant, and reasonably clean. The heating works well and wifi is fast. The location is also very good as it is a short walk to some of Istanbul's most important sites. The shower is a little odd and the kitchen is not massively well stocked with utensils, although you are unlikely to need them given how cheap food is in Istanbul. For the price you could do worse than stay here
