If you search for a nice, spacious & clean accommodation in Amsterdam for 2-3 people, then you should definately book that place! Of course it is not directly in the city centre, but it is an easy 10min. walk from the next train/metro station (Bijlmer Arena) from where you are very fast almost everywhere (20min to Centraal - 15min to airport). And if you consider the price, that is worth the little extra walking. Joek is a very nice host and can help you with everything I think.
