The flat looks pretty much like on the pictures, has very interesting and creative design and Emre is very friendly and nice host.
We mostly just slept there and did not use much (but some things are broken or look weary, nothing crusial though). There is kitchen stuff, Emre left us everything to use, even drinking water.
The flat is located on a very busy and noisy (in the evenings) street, in the center of Kadikoy close to Moda. The street is full of restaurants and pubs, but if you close the windows it's not that noisy. Bedroom at the back of the flat receives much less noise. Normaly on week days the noise stops around midnight, but on weekend it continues till 3-4 a.m.
The flat is located on the 4th floor without an elevator, but it's written in the description, so no surprise here)
In the close walking distance there are many restaurants, cafes, shops, market, ferries to european side, metro - so location is very nice and central.
Overall we liked the place and recommend it, having in mind some details written above.
Thanks to Emre for everything.
