Home in Istanbul. I stayed for 3 nights and it was wonderful to meet all three of them. Emre welcomed me during the arrival and Merve & Arif helped me during the departure. Before & during my stay, communication was super easy and quick.
The place itself is super cozy, comfortable & clean, exactly like in the photos. Easy access to kitchen & I had the bathroom for myself the entire time. In all, a very good base in Istanbul.
The neighborhood is called Omer Hayyam; and I felt very safe there. It has a local residential atmosphere which I really like. I usually left in the morning & tried to be back home around 8PM, so not too late in the evening.
I took the bus when going for sightseeing (there's a bus stop just before the underpass, going to Eminonu) & going back to the house I usually took the tunel from Karakoy or metro to Sishane; then continued with the historical tram & getting off at Galatsaray Lisesi (School) & walk through a small alley behind Istiklal Cad. (I believe they were Balik Sokagi & Sahne Sokagi), goes under the underpass, & continue all the way towards Omer Hayyam Cad.
If there's one thing you should pay attention to when you first arrived, is to have lots of patience to find the taxi that will take you there (took me 3 taxis before I found 1 who was willing to find the address & use the meter). If you rely on free wifi, perhaps upon arrival you can sit in one of the cafe / restaurant, normally they have free wifi, and use it it order an online taxi - cutting all the hassles. As for the rest of the trip, I used public transport (got my Istanbulkaart at the metro station in airport) & for going to the airport bus stop, Merve helped ordering an online taxi - super easy. A highly recommended place to stay in Istanbul!
