The apartment is indeed large and modern, the problem was the rest: it was filthy, full of dirt and dust everywhere. But most of all, when we were just outside the bathroom, a big dead insect fell off the ceiling (we have the photo).
The area is quite dirty and it has a terrible smell, besides it is at least 15 min walk from the city - overnight it doesn't seem recommendable.
The host did answer us immediately, but he didn't ever contact us before we did and therefore we had problems with the check in.
