I stayed for 9 nights.
Convenient for the Congress centre (5min) and Taksim Sq (10min) walk.
there are many little shops for supplies and eateries within 2 blocks.
Staff were helpful in arranging an airport pick up and confirming my ongoing travel arrangements.
Neat apartment with a small balcony and there is a washing machine you can use as well. The bathroom is tiny but not really a problem.
Main things for me was the smell of smoke when I arrived which was fixed by an airing out and I bought a deodoriser from one of the local shops. The bed was hard for my preferences.
