Deniz is a good welcoming and charming host. Makes you feel like home. Good Location at affordable price compared to hotels around. Clean and quiet neighbourhood. 5-10 mins walk from Taksim Metro station and 5-10 mins from Kabatas Tram Station. For Single Travellers, beware of scams who come to Talk and invite you in tourists areas...
I will definetely choose Deniz place when I come back Istanbul.
