The apartment is large and well designed. We were a group of 6 and we had a great time. In the apartment you can find tips on what to do near the apartment and other information that makes it easier to conduct in Prague.
The apartment is not in the center of Prague but adjacent to it there is public transportation so it is easy to move around.
For those who want to cook in the apartment, note that there is no oven and microwave (but there is a supermarket next to the apartment so you can always find fresh bread).
And another last note - if there is a sunny day - there is full light in the apartment even if you close the curtains, so you may wake up early from the light.
