Why it matters: the Solar bills itself as Paris’s first activist eco-hotel, running a real environmental policy (EU Ecolabel and Green Key certified) while deliberately keeping rooms cheap and hosting neighbourhood causes. Rooms are simple, but the organic breakfast and free loaner bikes are included, which is rare at this price. Book well ahead, as its reputation and low rates mean it fills up fast.
