We stayed at the hotel for 4 nights in May. We booked a Prague trip through a travel agency, and as I could see, the hotel is full of such tourist groups. The building is some 20 flights high and there are only 2 small elevators working. This creates a chaos when these large groups are arriving and leaving, but also at breakfast time.
We had a room on the 11th floor. The beds were comfortable, it was quiet and clean enough. For me, the biggest problem was the bathroom. It had no actual door, only a sliding plastic screen to separate it from the room. And it had no ventilation. The towels were changed, there was always plenty of warm water, but they didn't give us even the little hotel soaps, which is very unusual.
The location of the hotel for me was good, because of the metro station nearby. By metro, it is close to the center, so we could go back to the room during the day occasionaly to rest, which was a plus. The area is not nice, but i found it far from shady and unsafe after dark as I see people are saying. We returned to the hotel every evening almost by the last train and never had any unpleasantness.
The dining area is too small for the number of guests. It's crowded and you have to queue to get to the food. The food was the worst i had at any hotel so far. Everything was always luke-warm. the peaces of cheese and salami looked like they were cut days ago and were all sticky and tasteless. If something runs out, they don't refill it for a long time. One day they ran out of bread, and only refilled it after half an hour. There was a man making pancakes, but in a limited quantity, so we never got to them since we don't get up very early.
Overall, since the room was not dirty and noisy, and it was easy for getting around the town, our stay at the hotel was not horrible. But, i would not recommend it. At a standard rate of 100 euro for a double room, it is really not good value for money.
