Die Garden Appartement was great for us. The street which it lies on had great little shops and Cafés. The Appartment was clean and cozy and the view into the garden great. I would definitely come back. Kees and Marjolijn provided a variety of guides and Maps of Rotterdam, also the metrocards.
As a little side note: the Appartment doesn’t have a lot of windows, so it is on the darker side with lighting. Because we where exploring the city the whole day, that was no problem for us.
