The location: I've been to Prague twice now and this is the BEST area of the city to stay. Very close to public transport(5 min. Metro to city center) or you can take a 20 minute walk to the center of town. There's great restaurants and bars in this area that are literally a third the price of comparable food/drink in the city center.
The space: the space is exactly like it is shown in the photos. Clean, modern apartment with a nice little balcony. Exactly as advertised.
