Great apartment in a great neighbourhood (Fener / Balat). It's nice to be around the more real and quiet Turkish/Istanbul instead of the tourism crowds. A lot of laid back cafes and restaurants are just downhill. The area is upcoming, so be there before it turns into the next Karakoy or Taksim. Getting to the more city center things is easy with the bus or taxi, or walking for those up for it.
The apartment itself is authentic and cozy. Great terrace on top and even as great vibe. Moustafa and Ugur are a great help in coordinating everything concerning the apartment. Moustafa is always around, and very gentle and willing to help. And Ugur is always a whatsapp or email away with more detailed info if needed! Or even helping out with Fenerbahçe football stadium tickets :).
One minor thing to keep in mind though; it's an old apartment and after 4 days of full raining the apartment became quite damp. So our clothes and towels didn't dry as good as we hoped.
But that's really a minor thing and didn't get in a way of a fantastic Istanbul trip! Thnx guys!
