My sister and I stayed at Ece's house for five days, during our first trip to Istanbul. We loved everything about it.
Ece's house is in the Moda neighborhood which is in Kadikoy, located on the Asian side. It's boho, eclectic, artsy and less touristy than the European side. When we did venture across the Bosphorous, it was as simple as catching the ferry (an essential experience in Istanbul).
The apartment itself is gorgeous - filled with art, books and plants - and very comfortable. Plus, we adored Ece's sweet and funny cats who were around to keep us company (we're already missing them terribly).
Ece is a lovely host. She was communicative, helpful with local tips, and a lot of fun to talk to :) We're lucky to have had her as our host in Istanbul, and hope we will meet her again someday.
