Jean-Paul's place is fabulous! The location was about as best as you can get in Prague! It is located walking distance to everything in Old Town. It's located on the Castle side which is much quieter with tons of restaurants and pubs. Had my teen age kids with me and felt really safe in this area.
Would LOVE to go back and stay at Jean-Paul's again. BOOK THIS if you are lucky enough to come to Prague! JP's place is just as advertised, maybe BETTER!
