The apartment was extremely convenient and it was very nice to be on the ground level - no need to carry luggage up flights of stairs. Check in was simple, Karin had a friend waiting to let me in when I arrived. They had a bike available for me to use. I would definitely stay again if I return to Amsterdam. It is a bit noisy from traffic on the street and the apartment upstairs, but I was prepared with earplugs, so it was not an issue.
