The place is cute and it's indeed as beautiful as it is shown in the pictures. It is close to all the major tourist attractions, only there is a bit walk uphill to get to them (but you are in Istanbul, so you should be ready for walking up and down hills all the time). Barbaros and Anna (I believe she lives upstairs and takes care of the place) were very responsive; this one time the light bulb went out on a Saturday and we did not expect to have it changed until Monday (nobody really works on Sundays) so we were pleasantly surprised to find that the bulb was working by the time we got back in the evening (only a couple of hours after our request to change it).
There are many places to eat and buy snacks at around the place (there is a whole neighborhood where seafood is sold only a few steps away). If you request an Uber, it comes to your door very fast cause there are available Uber XL cars around all the time.
Overall, it was a great stay. Cozy and nice :)
