The apartment is absolutely amazing. It's huge with very tall ceilings and lots of light. It is located right in the center of Prague, we hardly ever needed to use public transportation, and mainly for going outside of the city, like the zoo or aquarium. The hostess is warm and loving. She even babysat our kids a couple evenings and went out of her way to make our stay excellent.
I think the pictures don't do the place justice. It is actually much more impressive in real life.
