The hosts are amazingly responsive and they guided us through our stay. The apartment is just like on the pictures, it was very clean and had all the amenities we needed. It gets a bit dark as it is on the base floor. We stayed 4 people and we were very happy with our stay. The listing is for 5 people, I think hosting 5 people in the apartment would be tough, it would be very crammed.
The only note would be the internet connection was not very great, it was sometimes dropping when all the guests tried to connect. All in all, we really enjoyed our stay.
