Berkan is most hospitable host I have ever met so far - helpful, easy to communicate, getting out of his way for you. Thank you again!
As for the place - building with old school romantic vibe, I could feel old Istanbul pulse. Felt like a local.
Location is amazing if you don't mind vibrant street life and constant novelty. During Friday/Saturday nights it was noisy in the part of the flat that looks to the street, so bring ear plugs if you have troubles with sleeping. Second part of the flat is quiet.
Planning to come back for sure!
