We stayed in Shinnosuke's beautiful flat for a week in April and we had such a lovely time. The host was so nice, he also gave us a travelcard with 10 Turkish Lira to get us started! He gave us a lot of information about Istanbul and loads of tips.
The flat is very nice, as it looks in the photos. And it's perfectly placed in the most exciting and buzzing part of the city, but tucked away in a secluded and quiet corner, with no noise from the nearby crowds. Plus free wi-fi!
I can't but warm-heartedly recommend it! Thank you Shinnosuke! :)
