Pros: Hosts are nice and helpful, they were willing to make my stay as comfortable as possible - were able to provide additional heater as I was cold; room was clean; it was possible to use washing machine (that was an important thing for me) and everything else that was in the appartment - kitchen stuff, etc.
Cons: 1) during night time it was not that quiet, sound of closing-opening doors was pretty loud (no soundproofing, but that's a usual thing in Kadikoy), so I had to wear my earplugs to get some sleep; 2) usually there was a mess in the kitchen, but it was not a big deal for me
Conclusion: a good option for the money, and the hosts are nice, smiling and welcoming people
