Rini´s place is really special. I was in Amsterdam for business staying one night only. Rini´s place was close to the office, close to shops, and close to the metro. It´s incredibly cool with the art gallery in the front, and a nice studio in the back. Rini made sure I had everything I needed with a stocked fridge and a bathroom literally full of soaps and whatever else you might need.
Would definitively recommend both for business or exploring the city.
