I loved my stay at Art Harmony. The rooms are awesome, clean, and comfy. Showers are equally enjoyable. Staff was very friendly and added to my enjoyment of Prague. I enjoyed my stay here a lot and would definitely recommend it to anyone. Really the only downsides I can think of are the gates are a little tricky to get through and it's not a party hostel exactly so if you're looking for a louder place with a bar and tours this isn't for you.
