Overall - the accommodation itself is quite nice. The apartment is just like in the photos, except for the fact that it's facing directly towards an old building (so, there's really no view from its windows/balcony).
This is a brand-new apartment, so you can expect everything to be brand-new. However, that also means that some everyday stuff is missing - like utensils, glasses, towels, and similar. You'll find those, but you'll get like a set of each, which makes it an issue if you're staying for more than a weekend.
Also, the check-in process is somewhat awkward since you have to call the host once you get in front of the apartment - even though there's a lockbox next to the apartment's door. And finally, expect the host not to be as responsive - before or during your stay.
