The room itself it quite large and it is in a great location (easy walking to the old town in 15 minutes). It is important to note that the walls are very thin and you can hear squeaky doors, plumbing (toilets flushing and people going to the toilet) even from upstairs. There is also a lot of road noise. We didn't get a lot of sleep during our stay unfortunately. However, for a short stay it is manageable. Prague is beautiful!
