Not a 4 star.
Rooms clean but basic.
Breakfast room was busy, food mediocre.
No bar in hotel.
Only 4 TV channels. No news or English channels.
About a 30 min walk to square.
Staff not very friendly apart from cleaners who did a good job.
Very basic hotel. Some much nicer and nearer attractions. If I were to return to Prague I would not return to ambience....
