Seyda and Alex are outstanding hosts - personal welcoming was extremely friendly, tips where to eat and what to see were top notch and taxi management on our departure date was outstanding. It is extremely hard to find a taxi with a baby seat in Istanbul, but they managed to get us one!
We traveled as 2+1 family and two bedrooms fitted perfectly for us, there is everything you need - a lot of towels, fully equipped kitchen and a bathroom with locally installed heater, so you don't have to worry to run out of hot water.
The one bedroom that is facing the street could've been a little bit better sound proofed, but it's nothing that robbed us our sleep.
On weekends there is a market directly in front of the house, which is charming :)
