The place looks luxurious in the photos, but it was not like this. Overall, it was a dirty place (especially the sofa and the toilet) and the bathroom had constantly an ugly smell. The top of it is that there where ANTS 🐜 everywhere!!!
It lacked of several facilities such as shampoos and towels etc. Thankfully, Volkan was helpful and responded to out demands, although we didn't meet him.
The location was very good indeed, but the neighborhood was dirty and noisy all day long.
I think that the apartment is very expensive for what it provides and for the standards of Istanbul. I would suggest to search for a room in a hotel instead. It's much cheaper and more standard. We chose this because it has a lot of critics but we stayed disappointed.
