This hotel is 3 minutes walk to the metro which is a quick ride to Amsterdam Central, the beds are extremely comfortable and breakfast was good.
We would stay here again, there are no frills but we didn't really expect any.
The only bad part to our stay was that every time the door to a room on our floor was closed, it made the whole building shake (it felt like). Our headboard would bang against the wall. I'm not too sure why this was, it did give us a fright at times!
Otherwise great choice for a short stay in Amsterdam.
