Overall this ABNB was great! Leon was fantastic at communicating with our group and met every expectation we had. The location also couldn't be beat! We were a short to moderate walk (5-25 mins) to all major areas, but the best part was being located right on a traditional canal. The neighborhood, as with most of Amsterdam, felt very safe and our group had no issues walking together or by ourselves.
The only cons of this ABNB, which are in no way Leon's fault, were the steep spiral stairs leading to two of the bedrooms in the basement. These types of stairs are very common in Amsterdam, though - be it in homes, bars, or restaurants. One member of our group did sadly slip and fall down the stairs. I would not recommend this ABNB - or any similar ABNB - if travelers have mobility issues or general issues with steep stairs. That said, this is more of a comment on stairs in Amsterdam as a whole rather than Leon's ABNB itself.
The only other con was the rather weak WIFI. It did not extend to the two basement bedrooms, but worked perfectly on the main floor and its bedroom.
Overall, this was a great spot!
