Giancarlos apartment really is a gem! I stayed a week with my grown kids and the nice flat really saved us during our stay. Even with a week of rainy weather the central location and the cute and the well thought-out interior made the saty really like being home. The design af the interior really was extraordinarily cute and Giancarlo is very easy to communicate with.
Note that you need to park the car some 4k away from the flat which wasn't an issue for us since we brought our bikes. Next time Den Haag, I'd try to book Giancarlos Chambres again
