The apartment is nicely located but a bit uncomfortable.
It's ok for 1-3 days stay, if longer the lack of simple things starts to bother.
Like there is no hooks or shelves by the door. We had to leave our jackets at the sofa(
No hooks or shelves neither in the bathroom - towel to the floor?
Kitchen is small and unequipped. Not even a turka for coffee in Istanbul.
Not a bottle of water at the arrival - which would be nice and cost nothing.
No cutting board, no towels, no microwave and not even matches.
No broom, brush and dustpan - we did want to clean up after yourself.
There were salt and oil though.
There are two apartments for rent. Since we needed good internet and apartments share wi-fi, we picked the lower one, where the router is.
It has a table as in a bar, taking over a small kitchen. So if you sit there, can't even open a fridge. Plus it's made out of marble the broken at some places sharp edges - had to keep kids away.
But the wi-fi was good and fast.
There is a nice cafe downstairs. Great capuchino 35 lir (2euro) + distant breakfast. You will hear people talking under the window all day, like a radio non stop. But it didn't bother us.

The location was great. Caffe, shops were near.
Yasin provided extra sheets, towels and a table for work when we asked him, fast enough.
Provided also a transfer, but it was pretty bad. Took us 40 minutes to leave the airport and for 50 euros car didn't come to us, we have to walk and look for it at the parking with 2 little kids in a huge airport.
All in all the apt will do for few nights.
For longer stay or if you need a kitchen, look for other options.
