Hansel is a fantastic host. He recommended a fantastic place to eat at a very good price. He is always available to help and open to communication.
The place’s location cannot bee better, within walking distance of the Sultanahmet Area, where the major tourist attractions of Istanbul are located. The flat is located in a residential area, so you will get to experience the day to day living of Istanbul. There are good restaurants and grocery stores nearby. The value for the flat is fair, considering its location.
As for the amenities, be aware that there is no microwave and there is no way you can prepare a meal in the apartment, so you will have to eat out every single meal-time. There is no washer, although there is a dry cleaning place close to the house. The flat has a small fridge where you can have beverages and snacks. The air conditioning is limited to one room and we were not able no make it work as an AC unit, worked as a fan only. The only negative aspect we could highlight was the floor cleanliness; which was less than optimal, specially under the beds or you move some of the furniture.
Overall, if you are willing to sacrifice some amenities for the location, the place has a great value. The garden has an amazing view of the Bosporus and is a refreshing way to end the day. Istanbul is an old city, so the flat needs to be judged in that context.
