Karin's place was just great for us. It's about the size of a hotel suite and very private. There is some chatter from the street if the windows are open, but it is remarkably quiet for being in the middle of the de Pijp. There are numerous eating and drinking establishments a short walk away and the Albert Culprit market is a block away.
Karin was very communicative and responsive and had a continental breakfast waiting outside our door each morning. We didn't meet but once, but we didn't need much guidance. She is easily reachable by email.
