We got the room for 2 people so by default (due to the site) we had to book a 2 room apartment so that's the kind of accommodation I am reviewing here.
The apartment was big, too big to be honest. The bedroom was comfortable, lightly furnished (which we greatly appreciated) and clean. The living room was even bigger. It had a sofa-bed, which we did not need but it's good to know it's there if more than 2 people are traveling, a tv and a desk. In a corner of the living room there is a small kitchenette with 2 stove rings, a microwave, a fridge and even a dish-washer. The bathroom was anything but crammed too and besides the comfortable hall there was also an empty storage room for you luggage or something. Everything was clean, maybe not brand new, occasionally, yet definitely well-taken care of.
It was quiet so we could get some peaceful moments and yet central enough to be close to transportation and supermarkets/bakeries etc within 5 mins walking.
Highly recommended if you are looking for something nice, quiet, clean and yet quite cheap. I am not sure why it's considered 2.5 stars when the rooms are so big and clean.
