We stayed for a week in Ali’s apartment, and for the most part it was fine.
First of all, it is incredibly well located, near two important metro stations and in the middle of a nice neighbourhood with a lot of options to eat when you get back from your day.
We also got the keys very easily and Ali was always quick to answer!
As for the apartement itself, it's small but it's enough if you're only two! The fact that it has two beds is nice.
Be prepared though: it is located below the street level so it's very moist, especially in the summer and the window overlooks the end of some outside stairs so it's not the most pleasant!
The first real problem we had is that it was not the cleanest it could have been, and there was no cleaning products or tools to take care of that. We also had to buy most of the usual stuff: toilet paper, sponge or paper towel.
Lastly, the apartment advertises a kitchen but what you really have is a cooktop who smells burnt anytime you try to use it and the kettle was so disgusting we basically couldn't use it . The microwave was fine.
To put it plainly: if you have a limited budget and you intend to use this apartement only to sleep, it's fine!
