We stayed here for 5 days with our 3 little boys. Miko's place was amazing -- we loved staying here! It's an older, very unique home -- the shape of the roof, the spiral staircase, the terrace on the roof all make this place special.
It had everything we needed, the kitchen had plenty of dishes, and the shower didn't run out of hot water! :)
It's located in a great area, walking distance to Istiklal Caddesi where there are tons of shops, restaurants, and street musicians -- we loved taking walks there in the evening with our kids.
Miko is a wonderful host too, we enjoyed meeting his family.
I think the only thing that concerned us was how easily you can hear sounds from the other apartments. It was not a problem for us (you quickly get used to the white noise from the city), but I was always a little worried that we were too loud for our neighbors. Due to the age of the house, it sounded like a herd of elephants every time our boys ran upstairs or downstairs. (And indeed, we had someone come ask us to be quiet towards the end of our stay.)
Otherwise, it was a completely perfect time, and we would love to come back someday!
