First up the location - probably one of the best in that its not in a totally crowded areas and not very far from all the attractions in the old peninsula. Its about 3-4 min walk from the Galata tower and the nearest metro is about 3-4 min walk the other way. We found it easier just to get to the trams at the Galata bridge (probably a 10 min walk) which is just a few stops from the attractions. The apartment itself is on a hill on cobbled lanes just wide enough for a car at a time. So if you have problems walking up and downhill, might want to consider. Great choice for restaurants, cafes, nic knacks, art shopping and 5 mins from the Sufi monastery where you can see the real swirling dervishes. Everything is open till 12 pm and everything is available within a 5 min walk.
The apartment - simply enchanting. Its on 2 levels and beautifully maintained with new age art & decor. 3 big enough bedrooms with comfortable beds and 2 fully functional bathrooms with washing machine. The kitchen is fully equipped with dishwasher, fridge/freezer adequate cutlery etc. Doruk has got a nice entertainment systems with sony/bose speakers all over the house. The wifi was very good and worked flawlessly, good speed too.
The host - one of the most professional hosts i have encountered. Everything was like clock work with Doruk and in his own words he has brought a corporate discipline to managing the apartment. He sent us a lot of material about Instanbul and all his recommendations well ahead. So we were totally prepared with what we wanted to do and see. He was there to check us in and explained every thing in such detail that we never needed to call him. He organised a private cruise on the Bhosporous for a couple of families in a very posh yatch for a very reasonable price. Was very helpful is getting us tickets to shows etc. Nothing was too much of a bother for Doruk. As expected he was there to check us out and even organised taxis to take us to the airport.
All in all, even if slightly pricey by Instanbul standards, the whole experience is just worth it. Would highly recommend Doruk and his apartment if you are a family of 4-5 people. Well done Doruk, hope to see you again in the future.
