I recommend this apartment very highly. It is spacious, extremely clean and comfortable. The bathroom, kitchen and television are all excellent. But by far the highlight is enjoying the 'Room with a View' - magnificent view in both directions of the Charles River and seeing the bridge and Prague Castle at dawn, sunset and at night. The location is so central and picturesque that I cannot imagine there are many hotels that could match it.
The young lady who greeted me was delightful - everything was efficiently organized, and the driver they arranged to and from the airport also very pleasant and reliable. I just hope whomever is reading this is not staying there when I next wish to visit Prague!
