The flat was acceptable. It was not perfectly clean and I missed Shampoo AND a Hair dryer in the bathroom. Luckily I didn't need them badly, but for a longer stay that would be unacceptable.
Also the fridge was a little moldy and the freezing part of it had a broken handle. It's basically not usable without hazard in my opinion.
Personally I had a very hard time sleeping on the matress since it was an oldschool spring matress, so very hard and uncomfortable. Luckily I only stayed one night though so it was ok.
To be fair, the flat is on the cheaper end in prague and it is very very central, so if you don't necessarily NEED some comfort, the flat is probably ideal for you. Also the communication with andrea beforehand and her father, who checked me in, was very easy and super flexible. She even allowed for a later than normal check-out.
