In short:
I do not recommend either an apartment (3* out of 5*) or a hoster (2* out of 5*).
In details about apartment:
The common area and the kitchen correspond to the photo and description. Problems with the bedrooms. They have tiny window and they go directly to the windows of the neighbors, so you can really shake their hand. In the bedroom with a large bed, the exhaust pipe of the neighboring gas boiler comes out exactly at your window - breathe deeper. The twin bedroom is very small in size, less than 9m2.
The apartment had a significant drawback in the form of an emergency condition of the wooden floor. Huge cracks with burrs and slivers are numerously located throughout the apartment. It's not safe. This is especially unsafe for children who can easily get splinter. In addition, the floor creaks loudly throughout the apartment.
The apartment has very poor sound insulation, so you can hear people talking, washing and so on.
In details about hoster:
I used the transfer provided by the hoster. the transfer is officially offered by the hoster along with other services. During the loading of luggage by their driver, my bag with valuable contents disappeared. So I lost the luggage that I handed over to the driver. According to the driver, my bag was stolen from him. My losses amounted to more than 2,000 euros. I did not get any compensation from the hoster at all.
