From the 9th-floor rooftop bar overlooking Sacré-Cœur and the stylish ground-floor cafe-restaurant to the vaulted basement bar-club styled like a Paris metro station, and supercool bathrooms with 'I love you' tiling, this ultra-contemporary hostel near Canal St-Martin is sharp. Dorms have USB sockets and free lockers, and the best doubles have fabulous terraces with views. Women-only dorms are available.
It's €7.50 for breakfast and €18 for a day's bike rental.
