Damir's flat was nicely equipped, (towels, laundry facilities, full kitchen and a plethora of guide books) located near Taxim Square and most of all QUIET. After a long transatlantic flight, it's nice to get some uninterrupted sleep and this flat provides it.
As some other reviewers have posted, this area is undergoing HEAVY renewal. This posed no problems walking around at night, but if you're off-put by dilapidated buildings and the element that it attracts, this might not be the place for you.
When our Taxi driver could not find the location Damir spoke with him twice on my mobile to get us back on track and was most helpful on arrival with getting us orientated and offering a few Turkish snacks.
As well, do make sure to check out the Istanbul Eats guide book, if you like good food, you're going to be in HEAVEN in Istanbul and most establishments are within walking distance or only a small cab fare away.
In summation the flat was nice and QUIET cant' emphasize enough how nice it is to get away from the hustle and bustle for a few, Damir easy to deal with and most competent host. But if you panic when you aren't walking red carpet lined streets this is not for you.
