Oski's place is not the Ritz but is is very warm and cosy and feels like home. It's clean and comfortable and surprisingly spacious, located in a quiet part of Kadikoy and close to fabulous places to eat such as Bop of Pan and Kuff as well as good coffee at Cafe Mu. all, just around the corner. Plus, of course, plenty of others only 5 minutes away.
A walk to the ferry is literally 5 minutes down the hill and I believe the Metro is similar distance (but why use the Metro when you can go by ferry?)
Loved it and will definitely stay again.
