Hi.
Kardo is an outstanding host, communication was really good, flexible check-in and check-out. Location is perfect however a bit noisy at late night during the weekends due to proximity to pubs and bars.
It's located at 4th floor so be mindful of carrying heavy / large luggage up as there is no lift.
Main downside is lack of curtains, so minimum privacy and too bright to sleep specially during sometime.. don't forget your sleeping eye blindfolds.
Regards
