The flat was just fine for the price. Very good locality, which was convenient.
Only small things which weren't so great.
Small towels, really (basically non existent) pillows, no shampoo or shower gel...
Also just a single bed and a not-that-comfy couch. But the place was well located as mentioned above and it was quite ok for two nights. Would not recommend for a longer stay unless you are on a budget and you don't mind basic.
It was nice that we could use the kitchen and I also liked espresso machine, which was 1 EUR extra.
