After my forth trip to Istanbul in 5 years I can say Akif's space is in one of most strategic locations of Istanbul; In walking distance from Bosporus water narrow and Golden horn (including its public transport)... Almost next to Galata tower... And In 15 minutes walking distance to Istiklal street (Note this last one is uphill).
A very great privilege of this home is its roof terrace (Note it is shared on the roof of the entire building, three floors upside and not a private terrace of the apartment) with amazing view of the golden horn and Bosporus waters.
The space is warm in winter with no problem and bathroom water is hot enough.
The space resides on 3rd floor using stairs and no elevator, not a problem for younger travelers but an old one may consider this.
