I would recommend avoiding this apartment and this "host" - the management company - altogether. The apartment has a couple of issues, but the worst part is the overall attitude of the company.
First of all, there's a strong swage smell coming from the bathroom. The host blamed it on the building, even the city itself and if you are to believe them, it's unfixable. To quote them: "there is a smell but it is something that it may be happened in Athens". So expect a swage smell.
Second, the boiler room is full of mold. There was a boiler leakage unsolved for a long period of time which resulted in the room staying wet and mold forming.
Third, one of the balconies if full of bird excrement. It looks so bad that either all the birds in the neighborhood are staying above that balcony, or they haven't cleaned it in ages.
As for the host, they are just trying to hide the issues with the apartment and avoid taking responsibility or fixing the problems. As an example of their attitude: the boiler was leaking for a long time before we arrived at the location. Instead of fixing the boiler they had placed a small dish to capture the dripping water, but the leakage was so bad it had overflown for so long that mold formed in the room.
