Very good option to visit Amsterdam. Just in the Westerpark area, And this implies you are close enough to the touristic centre and close to a very beautiful neighbourhood. There are good options to spend a good time just crossing the little canal: breakfast (BakkerWinker), dinner (Mossel gin foodbar) or even drinks and music (Northsea Jazz club music).
Yes, the apartment has no elevator (just like many in the Netherlands and Belgium) but it has good windows, it is big enough and equiped for a couple to stay some good days in Amsterdam.
Carla gave us the instructions and recommendations we needed for a good stay. We will return.
