The Nova apartments are just perfect for anyone visiting Amaterdam. Their quiet museum district location is excellent, and they come equipped with everything you'll need. Nice bath, wooden table for dinner, cooking gear, microwave, dish washer, LCDd and free wifi. There is a big supermarket within 5 min walk (credit cards not accepted but there is an ATM machine for cash), parks, street markets and canals spread in a one mile radius.
The best thing is the value for money: beats any hotel. The room is cleaned daily and while I didn't use it, there should be someone on call to help with stuff over the phone. Ironing board and plenty of electricity plugs cater for the business travelers. Overall it's a great find.
