We were a 9 people group, 8 adults and one 5-year-old Child. traveling in EU during summer time, A big family. We lived in a great location in Prague. Everything is so close to us, it was convenient.
There's are everything in the apartment, so that you can cook, wash the clothes, and sleep. Sleep for 8 people is quiet enough. I mean, everyone can sleep on a bed.

On thing you need to know is, there is no air conditioner. There are two rooms in the half of the floor without WINDOW. Although is not that hot in the night, during the summer time, so that you can open the window, let the fresh air in. But the two rooms has no window to do this thing, then, you would get too hot and stuffy to sleep.
There was 8 girls and women in our group, so, the safety is important to us. The neighbor are some strange people, working in the night. Two mans would seating outside if we open the door look at our left hand side, we would see them. Then some girls and men crossing our door during the night, is kinda scared us.
