Very nice, clean and comfortable apartment. 5min walk to Taksim and shopping streets.
Cons: The windows have no shutters (like every other apartment in Istanbul), so it is very bright by 6.30am. The AC is installed in one of the bedrooms so it's pretty hard to cool down the entire apartment. To do so, you must set it to the lowest temperature and the people staying in this bedroom get pretty chilly.
Pros: Very cozy, good wifi, central location (nice street with cafes), very clean space and with everything you need for your stay.
