Place is hard to find, even though you use google maps or similar. Taxi drivers had a hard time finding this place also. Our taxi driver got tired after a while and just suggested to drop us off somewhere so we could continue from there by foot. So if you have lots of luggage this place might not be for you.
Once you are there the location is perfect, just a 5 minute walk uphill to Istiklad Cadessi and you are in the middle of the Istanbul shopping street.
The place is extremely clean and modern. Supereasy check-in through the pin-code on the door. The only thing that was annoying was the quality of the walls/ceilings. You could hear each sound that your neighbour or the person above you would do. So somebody who prefers a more private setting should look somewhere else.
