The only caveat to consider is that there are no window blinds, probably due to the historical nature of the building and the area itself.
There are drapes, of course, but if you are someone who needs complete darkness for their sleep then you won't be entirely happy.
Otherwise, the apartment is very nice with comfortable king size beds. Ideal for a family of 4 or even more if the children are small.
The neighborhood is quiet and we were able to park our car just outside the building.
Prague is wonderful and we enjoyed our stay very much.
