We spent here 10 days and it was great time.
First impression is Muhlis - sooo helpful and caring. provided us with huge bottle of water + snacks and yammy nuts + his own "to do/to see things in Istanbul" + was so generous that allowed us to stay additional hours as we had a night flight.
Another bonus is books in English like Dalai Lama "the art of happiness" which i enjoyed a lot.
Location could not be better. Just 7 min walk downhills and you get to the GalataPort where u can walk and have coffee watching sea.
Fully equiped kitchen + washing machine is another big plus.
I highly recommend this place to others and will be happy to return.
