The bathroom is shared with 2 other bedrooms (probably 4 other people), so take this into account if you are planning to go out at a certain time.
Our towels had a weird smell. The small pillows on the bed as well.
The common area is not ventilated at all. So it might be uncomfy to be there.
The room was very spacious and well equipped: closet, hanging racks, a sofa, a desk with a mirror and lamps, chairs and a fan. The bed was big enough for 2 people.
The location is great: it is a walking distance to Wenceslas Square, to the main station, and even to the old town.
