I booked this place for 2 days but ended-up staying for full 4 months, just because of the the host, the vibes and the location of this place.
It's a perfect place -- clean and comfortable -- the host is smart and sorts out problems irrespective of which language you speak.
The location is so central and convinient (a huge super market and good restaurants in the same building). A metro by 5 mins walk, a major bus station by 10 mins walk, dolmus (small busses) by 10 mins walk and typical Turkish cab station at 5 mins walk.
The kitchen and bathroom are always clean and usable at all times. I'm a traveller and this is my spot, any time I'm in Istanbul. The Turkish hospitality in full force here, I stayed -in at other places, not a good experience.
This felt like your own house and the host felt like a true brother. Cheers!
