Great place with great location. It is like on the pictures. Host was very responsive and gave us all the things we needed. Place is near Suleymaniye mosque (2-3 minutes walking). Also, Grand Bazaar is near (5 minutes). You can walk to any station you want (Beyazit or Eminonu) where you can catch a train, metro or ferry. The surrounding are quiet and you have restaurant in front of the doors if you want to eat quickly.
The only bad thing was cleanliness. In general it was good bedsheets and the room was clean, but you can see dirt on kitchen and in the bathroom.
