It was without doubt one of the best AirBnB's I've been to. The location was amazing. It is right down the galata tower filled with antique bars and store. They did a modern renovation (in the old vintage neighborhood) and the room was super clean and bewildering. The bathrooms were surprisingly clean and the bedsheets and mattress were absolutely high quality. The kitchen was equipped with IKEA equipment's. The sleeping quality is perfect and the safety of the flat is controlled by trained security. The best part about the BNB was it's lovely balcony in which is a great place to hang out for hours.
I defenitly would choose this place for my next trip to Istanbul.
