The house has potential to get a 5 star rating.
Location - Nice residential location, 5 mins walk to istiklal cadesi and 3 mins walk to cafes and restaurants. Tram is 10 mins walk.
House - No air-conditioning. Host said the house stays cool enough due to shade and opening windows brings in cool air (which is true), but then you can't leave the windows open as cats will visit. I have cat allergy, so was in a tricky situation.
Price - I think for $45 per night, you can get better stays.
The car park manager outside the building is a super sweet man, and offered us help in very genuine way. Overall I felt all Turkish people are very sweet .
