Had a lovely time at Chamres D'Amis. It's a bright, well located flat (easy to park outside, 5 min walk to train station, 15 min walk to centre) full of cool designer touches, which my kids loved. Giancarlo is friendly and helpful and the vibe is relaxed. Very comfortable beds too, so we all slept well.
Would thoroughly recommend to anyone looking for a short break in The Hague.
