The place has really good location - it's literally 2-3 minutes away from Taksim square.
The balcony is very spacious and we really enjoyed the look and the option to drink out coffee there.
Isik was great host - very fast at responding and we got all the information we need.
The only thing that I can recommend is the Internet connection to be a bit faster. It could be only during our stay, but sometimes we had troubles with streaming.
