The apartment was not the same as all the photos. Furnitures and other interior was mostly the same, but e.g. the layout of the apartment and the placement of the windows were not exactly as in all pictures. In addition there was an extra separate bedroom with a single bed.
The access to the courtyard is nice, its a calm, green place to take you meals.
The apartment is situated very nicely, close to the river, 10 min walk to the conference center and about 15-20 min by tram to the centre of Prague.
Be aware that even though the apartment is in the ground floor it is accessed through 4 flight of stairs (>40 steps), which is nice to know coming with children or a pram.
Communication with Prague Days was very fast, but a bit unpersonal.
