I stayed a couple of times at the Kampa Hotel. The rooms are tiny and have no air con. But the rooms are clean and the breakfast area is awesome, even with live music. The location is great, just 5 min walk from the Charles bridge. On the first time it was hard to find the entrance, it’s in a side street with a small hotel sign… I rate this hotel just with 3 stars, because the value for the money and the receptionist are not fluent in English.
