We really loved our stay!
The space was immaculately clean, had nice modern amenities, was a decent size and is wonderfully located, with a balcony overlooking Václavské nám (Wenceslas Square).
We were only a few hundred meters from all the tourist spots and going in the other direction took us to a more 'normal people' version of Prague. It's right upstairs from two subway lines and a block or two from many tram lines. There is a grocery store 50 meters away. All in all, this was an excellent choice for us to explore Prague.
