Everything was ok,near Taksim square,clean and comfortable room,good breakfast,quiet hotel,but the most important is that you don't feel like staying in a hotel,but like you are a guest in a friend's house.Cagdas who is the owner and the other employees,will help you with advising you with places to visit,how to get there,they even will provide you with umbrelas when it's raining.I have been in Konstantinoupoli many times,and i think it's the best hotel i stayed,because of all the above.
