Lovely flat - well furnished, very clean, nice quality bedlinen and comfy beds. Small kitchen but served our needs very well. Very close to all the sights - a great base for seeing Istanbul Sultanahmet.
Local area is very hilly, so if mobility is an issue this might not be the best location for you, but it caused our family no problems.
Tevfik and his team were all very helpful and friendly, offering advice/recommendations whenever required.
Happy to recommend this apartment.
