I rented this apartment with my family of 4 for a month and we had a very satisfying experience.
Dr. Tufan was highly available and helpful. Before our arrival he was understanding and let us shift our dates and after he helped us navigate the area with providing information of all convenient places around us and responding to any issue we had immediately.
The check in/ check out process was very smooth and flexible. The apartment was acceptably clean and in a great location that felt safe and convenient.
The street itself is not busy and cars cannot enter it which provided a little bit of distance from the busy buzz of the highway but at the same time the building was located just a few meters off the main street which was convenient enough for transferring luggage to/from cabs.
Of course Istanbul downtown is very busy and for us the traffic noise was a small sacrifice compared to the convenience of the location. We didn’t lack for anything. Stores few meters away had almost everything. Groceries, pharmacies, good food places and even currency exchange at good rates. In addition to bus /metro/ and metrobus stations that connect to most touristic attractions in Istanbul.
I also want to comment on a couple of reviews I saw on this listing that complained about the lack of drying rack (which was available in our stay) and lack of change of sheets (which we had only to ask for and Dr Tufan sent the cleaner to replace them with fresh ones).
The only inconvenience might be the size of the small bathroom/sink as it can be mildly annoying especially to someone of bigger build.
Overall we enjoyed our stay and would love to rent it again in the future.
