A mixed stay.
On the plus: Great location to explore Prague on foot, reasonable price, friendly and helpful staff especially for transfers to/from train station and airport, good breakfast buffet, very large room, good aircon.
On the negative: Only appears to be a 4* hotel due its location and room size. No bar, no room service, very noisy with trams passing by very close by and little sound proofing to corridor outside, broken shower, very recently installed smart TV not setup and completely unusable due to antenna being disconnected any anything else needing a Samsung login.... staff did not seem to know anything about it.
Could be a great hotel with some small improvements.
