The apartment is very well situated on the "other" side of the Centraal, which I enjoyed very much. The nearby parks are a treat - check them out!
Floris is a very good host - checking in from time to time - but lets you be if you want to. He provides a little guide to the apartment and Rotterdam - which was very useful and inspiring.
The apartment is a bit "different" with its layout of two floors. But it is very well maintained and I think it is very authentic. The bedroom is on the top floor - which gets a bit warmer in the summer time (airflow is still good!). WiFi on all the floors - with seamless connection. The little nook - with a height-adjustable desk & chair - makes life easier (if you need to work). The kitchen provides you with everything you need and their spice rack is impressive! :-P
Enjoy the sun in the mornings on the little balcony - and in the evening you get some sun rays in the living room. Overall: a lovely, authentic and well-maintained apartment with great hosts.
