Great value for money in the Haag, and even more so if you compare with Amsterdam. The flat is nice, I would say like a nice big hotel room but with better equipment (for doing laundry for instance, preparing a salad or pasta). It is not brand new but it feels authentic and cosy. The beds are rather comfy (two simple beds side by side that you can "hide" to have more room during the day).
The neighborhood is nice and very calm: the city center and the central station are both accessible by walk but you can also take the tramway.
Tom is a very nice host, he lives downstairs which is very convenient on arrival and departure.
