Klara, Ondrej, and Anna were excellent hosts. I was having some trouble with a few things on the first night and they responded to my messages extremely quickly, with care and a desire to help, even though it was late at night. (Thanks again!)
The apartment is excellent. Clean and with everything I needed for my stay. It is right in the middle of the Jewish quarter, with the Altneuschul on the one side and the Old Jewish Cemetery on the other. It is also right by all the action in Prague 1.
So, yeah, I recommend this apt to anyone coming to Prague. Enjoy :)
