Amazing apartment in exactly the right location to catch the light rail for access to whatever sights you want to see in Istanbul. My family and I enjoyed our stay - very easy to check in even when arriving at 2 am.
This place can sleep a lot of people - they have two sofas which pullout, one murphy bed, two twins and a queen/full. This was perfect for our big family with lots of kids!
You are two blocks (downhill) from the light rail and 1 block (uphill) from solid restaurants (I like the Italian place at the end of the road - owner is a great guy who is from the neighborhood).
I recommend booking with Rose and Mustafa - you won't regret it!
