The apartment was exactly what we needed and hoped for.
First we met with Fatih Kaya who showed us the way to the flat. It happened very smoothly, even though we had a huge delay due to our flight and arrived very late in the evening.
The room is as depicted in the pictures: comfortable bed, small kitchen, nice shower, air conditioning (which proved its use during hot summer days/nights) and finally a perfect location (close to a small supermarket, very nice restaurants, the Galata Tower, tram stop "Tophane", metro "Sishane", the Galata bridge, Taksim square).
On the downside we could hear every noise coming from the street (drivers like to honk a lot in Istanbul, kids playing in the street) and the wooden floor is quite loud (our floor as much as that from our upstairs neighbour).
We would definitely recommend staying here, be it for a short or long time! Thomas & Dijana
