Staying at Oya's place was an incredible and wonderful experience! I felt like royalty, and heavenly, also because of the breakfasts they served daily!
I met both her children, and they were fun to hangout and get to know. The location was perfect. 7 minute walk from the Metro and Istiklal street, and buses from the airport.
They had a construction project in the next street, but noise was only heard after 9am.
Other than that, the house was warm, coszy, richly decorated and wonderful to spend time in, but some of the street noise could be heard from the bedroom window's at night.
The bed was comfortable, but I am 5ft 10, and my feet stuck out past the bed.
I'd really recommend staying at Oya's place! The best experience I've had in Turkey : )
