The accommodation was part of a hotel, and I guess Kamil handles sales for them. The hotel staff were very helpful and very courteous - special shout out to Tom who was so so helpful - with local restaurant suggestions, public transport, etc. The hotel room was quite nice, though showing some signs of wear and tear. But at the price we paid, no complaints :) Great to have complimentary mineral water everyday, and the breakfast was good too :) The terrace has a good view of the Blue mosque. The sea view is a disappointment (both from the room and the terrace - there is construction on the main street, Kennedy Caddesi, and so the cranes ruin the view).
Will definitely consider staying here if we are back in Sultanahmed!
