Perla hotel is convenient... it is of walking distance to many places of interest - old town and wenceles sq. It is also near the subway station. I really liked the interior of the room - it was very stylish and contemporary and very clean which makes it a really pleasant stay, especially when Prague was my last stop of my europe trip last June. The breakfast every morning was sumptuous and a good array of food. It was also not expensive and fitted very well into my budget. The room was not big, but it was small in the warm and cosy sense. I stayed here for 3 nights and I slept very well throughout.
