Zalal was very friendly.
We loved the apartment! There were 2 of us, but it could easily be used by up to 8 people I believe. We had everything we needed. And of course we loved the view from terrace!!!
The access is a bit hard if you are walking uphill from Bosphorus and then to the top floor, we are not that sporty, we made a couple of stops)) Getting to Taksim is a bit easier - about 3 minutes walking up, not a problem at all. All that walking up and down wasn't a big issue for us, anyway if you are overweight or having problems with legs/back, I believe this will be a big problem.
