I stayed here with my son. Fantastically central location, a two-minute walk from Charles Bridge. The apartment was simply furnished but spacious, airy and cool, and with simple kitchen facilities (fine for making breakfast) and a good bathroom. There's a lovely cafe (drinks only) in the courtyard downstairs. The only drawback was that it was quite noisy at night (it was warm so we had the windows open), primarily with drinkers out in the street at the pub around 50 metres away.
