I stayed at Rosie's B&B whilst visiting Amsterdam for a conference at the Rai exhibition centre and it was perfectly located, both in terms of access from the airport and the daily walk to work. The room was light, spacious and quiet with shared bathroom facilities right next door. The separate access is also perfect for those who prefer a bit of privacy. Unfortunately I only met Rosie briefly as she was away for most of my stay, and my early starts meant that I was unable to avail myself of the full continental breakfast usually on offer. Would definitely recommend to others in town either for business or pleasure.
