Furkan was very kind but when we arrived we were surprised that no air conditioning was provided which is really mandatory during summer time... (some other flats in the same building have some basic air conditioning...) The flat has three electrical fans but that's really not enough during summer... the flat is located on the third floor (very steep stairs) and the terrace on the sixth floor... also the bathroom and especially the toilets where not cleaned at all and the rest of the flat was just ok... During night time we found the building a bit noisy especially when you have to sleep with the windows opens... the main good point is location which is indeed very convenient to visit Istanbul. I would also recommend any traveller to take a taxi from airport to the flat as it only cost 40-50 turkish lira max.
