We had a great stay in Prague, no small thanks to Lenka's flat. The location is ideal so you can walk to the old town, but with public transport just around the corner if you need to go further. The flat was well-equipped, with plenty of space for the three of us - we especially appreciated the firm mattresses on the beds. Even though the flat is near to a busy intersection, inside the flat it is quiet, as it is facing a courtyard.
Finally, we would also very much like to thank Davide for his tips on where to find the less-touristy, off the beaten track sights.
In short, we would certainly recommend this flat!
