Bastiaan's penthouse is the best place I've stayed at using Airbnb by far! The interior is exactly as shown in the pictures, and it was very tidy. It also had every gadget and amenity you would find at home. The sofa bed is very comfortable and can sleep two. My family of 3 enjoyed spending our morning and dawn out on the huge terrace. The location is as described, within 15-minute walking distance from most of the attractions; not to mention that the Waterlooplein market is right below the building. There are also supermarkets, coffee shops, and bike rentals right below. The check-in and check-out process was very smooth thanks to Bastiaan's neighbor. I would highly recommend Bastiaan's penthouse for all travelers to Amsterdam!
