I stayed for only one night at the Wyndham Grand in Kalamis, during a 5 day business trip to Istanbul. The experience was extremely good, helpful friendly staff, the hotel had a very pleasant aroma throughout, the room overlooking the sea was bright and the bathroom spotless. The staff at the rooftop bar were more than accommodating, as were the restaurant staff. I plan to stay at this hotel next time in Istanbul even if the location for meetings is not as convenient as others. This was my first visit to this hotel but I will certainly be visiting again.
