Tugba and Aytac`s place is as described on this site, and so much more. I had booked it for one month and ended up staying three months (and I will come back for sure). I would recommend this place for long-term and short-term stays. The place is clean, comfortable, and quiet; and the hosts and neighbors are very nice. Balat is a gem when it comes to discovering old and new Istanbul, with the tram, bus, and ferry rides at a walking distance. You get to see Istanbul without feeling a tourist.
