Excellent aparts!
Location is best for Istanbul: Blue Mosque, Haia Sophia, Hippodrome, Topkapy and other points are in walk access.
Tram, metro and Marmara in walk access.
Restorants & cafe, shops & souvenirs... But prices are expensive: it's tourists area. Be careful with local taxi drivers - they are very-very "good businessmans".
Aparts was very clean and comfort, fantastic sea-view to Marmara see with giants ships going to/from Bosphorus...
It was very good days in Istanbul.
Thank You, Ercan and team!
