Stayed here last October.
Rooms are TINY, showers are even smaller, they are basically 1x1m boxes with shower over toilet. The water doesn't go anywhere and stays on the floor for hours, so if you want to go and put your clothes on and then revisit the bathroom you will stand in 20 cm of water on the floor.
The shower water itself is so disgusting that there are no words to describe it - I basically had to step over all my senses to take a shower there - it's just rank, feels like the water is taken directly from the river. Water from the tap was OK for brushing teeth, etc.
The walls are so thin that you can hear people going to the toilet - believe me, it's not something you want to experience.
Restaurant staff was very rude, the girl who served us has heard something wrong and brought us too much stuff, after we told her she got quite furious and told us that she will now have to pay for the extra order... welcome back to USSR. I need to mention that this place is very popular with very large men wearing sport suits.
I also don't quite understand the "Art" part from the name of this prison boat - there is nothing arty about it.More
