Perfect apartment and location! My wife and two kids(3 and 6 years old) stayed for three nights.Its a duplex unit which bedrooms are upper floor.Handrails fixed for stairs.
The apartment itself was safe, lovely and we were very happy to retreat to the flat after a busy day out in the city.
Nice having washing machine and full kitchen. A very nice touch was bathrooms were stocked with basic toiletries and the kitchen stocked with basics including fruits, water,soft drinks, butter(all free of charge).
The location was wonderful. Safe, lovely street, with many restaurants within walking distance.
Tube stations also easy walking distance. Other attractions including museums, palaces, parks walking distance. Also very easy to walk one block to a main street and catch a taxi.
Overall, we were very happy and comfortable and would not hesitate to rent the flat again when we return to Istanbul.
