Lovely flat with high ceilings in a very central location close to the old square and Charles Bridge. It was snowing while we were there so we appreciated the excellent central heating. Lots of big windows so can imagine the apartment is cool in summer. Nice cafe (Pauseteria) at the end of the road (less than a minute walk) for good coffee and breakfast. Very grateful for late check out as our flight not til evening.
The apartment is 3rd floor with steep stairs (not suitable for anyone with mobility issues), and the toilet macerator was a bit annoying in the night if you have a partner who gets up to use the bathroom.
