I stayed at Adriaen van Ostade B&B when attending a conference at the RAI Conference Centre in Amsterdam. From the B&B, the conference centre is a very pleasant 1 km walk along a very direct route. I was in the top floor room, which required climbing four flights of stairs which are narrow and steep, but they weren't a problem for me and supplemented my daily workout. There are many restaurants, bakeries and a nice supermarket within a few blocks. Jasper is very friendly, helpful and accommodating. The food is high quality. The amenities are excellent. The wifi is high speed. The room was quiet, comfortable and clean.
