Having arrived around 8pm the check in was swift and courteous. The location is good for tram 5 and 12 to Holesovice Station and Tram 12 to Malostranska and Smichov Stations, Tram 5 operates to Hlavni Nadrazi Station.
Very nice and friendly staff! Parking actually is not for free. It costs around 8 Euros/day. I think this has to be changed in information at booking.com. Otherwise everything was excellent.
