Isik is a veteran host with perfect planning. He provided detailed information on how to reach his flat with the mode of transportation of our choice and several ways to contact him in case we needed anything. The provision of a public transportation card is a nice touch, however it pays off to buy one at the airport if you take the metro from the airport public.
The flat is just a couple of minutes from Taksim in the 3rd floor with one of the steepest staircases I have ever encountered.
Walls are very thin, so any neighbor talking, moving or using the staircase makes you want to check the apartment for burglars.
Taking into account the low price, I would still give a 5 star rating.
However, due to a build-up of mold in the shower (in an otherwise very clean apartment), I give 4 out of 5 stars.
