Nice and clean apartment in a very convenient location (few minutes walk to wenceslas square and 10min or so to old town). Apartment was a little cold even with all the heaters turned on but bearable. Despite being in the red light district, street felt safe and was quiet throughout the night. Above all, the hosts were absolutely sensational: almost instant replies to my messages as well as organised maps and transport for us to/from the airport. Will stay again if I go back to Prague.
