It couldn't be easier, a shuttle bus to Taksim Square from the airport, a 7minute walk, and you are at Nihat's. Nihat is very laid back - knowing that he is presenting a very affordable and well kept home close to all needs (transport, shops, even a Macdonalds if that's your thing). He is very diligent in responding to all forms
of communication asap and is a clear pro. at airbnb hosting. He thinks of everything and opens his house completely. We even laid back watching tv one night - so I got a sense of home away from home.
The house is on the 4th floor - no elevator, but that isn't a bother unless you are bringing your life in a suitcase. It is spacious clean and tidy. It is next to Taksim square which has its history but is as safe as any main squares in any other modern city. The metro is 3 minutes up a steep hill. Or you can walk the other direction 3 minutes and be on Istiklal street (again up a steep hill) - mentioning the steep hills for anyone of an age or disposition - but for an averagely fit person this is not a big issue and most of this part of town is up and down hills.
Nihat rents out two rooms. The smaller (single bed) is perfectly sized with an air conditioning unit should you need it, an empty cupboard and safe for person belongings. Bed again clean and comfortable.
In a city with some dubious airbnb choices/ stories/ feedback, there is a reason Nihat's is always getting booked (from what I saw firsthand). If the location is right and you can manage a hill or two then Nihat's is the right choice. Don't hesitate, book it now. I'll def. be recommending Nihat's.
