Willem is a nice host, we always got quick respond whenever needed. The apartment is as in the pictures and location is very good. We were with small child and he had enough space to crawl. The apartment is on the 5th floor but there are two elevators, so no problem with lifting. Big supermarket is 5 minutes walking distance. Willem also provided baby crib and high chair.
There were even small size shampoos and dishwasher detergent in bathrooms and kitchen which were very useful until we settled.
There were some problems with water pipes, but they were fixed while we were there.
I totally recommend this place.
