I was doing a trip around Europe by train with three friends and the apartment was very close to the train station. Praha is a great city and the location was very practical. The fact that the flat was beside a big road, noise was somehow bothering but with ear plugs, it was survivable. The wifi access was quite deceiving. The place is how we expected it to be after reading some reviews but we didn't want to complain as most of your time is spent in town.
We still had a great time !
