This studio is in a fantastic location. You have anything you need around you. Plenty of shops. Two metro stations. A shopping mall. Many eateries.
Koray is a very good communicator. You can message him and he replies immediately.
The flat itself is clean and tidy. It's a top flat that is up a few flights of stairs. Do bring earplugs though as even if you are at the top the big din from next door's loud music carries on early in to the early hours of the morning. Overall a very good location, but ear plugs required.
