I lived in Prague some years ago, so I know it quite well. This was a return visit to see friends. The location of this rental is great. Lots to do in the neighborhood, easy access to the touristic center.
The apartment is clean and well furnished. It is as described on the site, with no worrisome surprises. Marina is easy to deal with, communicative and helpful.
We stayed four nights and will probably stay there again... recommended without hesitation.
