I spent another great weekend in Prague, and the accomodation added a lot to this positive experiment. It is a nicely refurbished and fully equipped modern apartment in a quiet and safe neigbhourhood. Not in the center but with good links with public transport at day and night. The flat is on 3rd floor with no lift - should this be a problem for someone - it was not for me. :) Absolutely recommended.
Annette is a super kind host, taking care of her guests, I had a very pleasent stay.
Many Thanks again for your hospitality!
