There's a reason that the line 'this is a rare find' came up when I was searching for a booking in Prague - it's because this apartment is exactly what Airbnb aspires to be all the time (in its wildest dreams... ). Just book it, if it's available. Super-convenient location, super-communicative hosts, great movies on the TV for chilling after a day of sightseeing.... Nice shower... Well-appointed kitchen plus washer... Literally steps from the main square...
