Eren’s apartment is clean, very spacious and equip with basic amenities such as washing machine, heater and good kitchen. Eren is also very responsive though I suggest he should make a standardized message explaining about his apartment location eg google map (the taxi we took from the airport was not familiar with the neighborhood. Travel advice: the nearest building easy to locate and just across the building is Hammamhane hotel), his phone number and other information needed for check in so no information is missing once booking confirmed.
On the other important note, the apartment is located in Çukur Kuma area which was mostly filled with antiques and boutiques/cafe and a short (hike) walk to Istiklal street. However, the road is a one-way street and very narrow (so we often get our taxi driver cancelled from Uber) but this is not a major issue as you just need to go a little down the road where the road is much bigger near Karaca pastry shop
Also I’d like to personally thanking Eren for allowing us a late checkout as our flight was booked at 7pm so we still can enjoy and stroll around Istanbul in the morning and have a decent rest on our last day
