Leon was away at the time of our visit but he gave detailed instructions on how to access the house. He kept in communication before our stay answering any questions we had.
We loved the unit, it was clean, filled with light, beds very comfortable, facilities great and easy access to public transport. We found it an ideal (& lovely) location close enough to the Central Station without being right in the tourist busy areas.
Leon was kind enough to let us leave our luggage for the day and all we had to do was pick it up after being out and about for the day.
Leon left brochures on Amsterdam in the kitchen which were very useful as well.
