The sole London branch of a popular and well-run Spanish brand, the H10 is a recently built tower, so rooms are nicely sized and modern, with art that actually speaks of good taste, with a bonus of having a healthy floor-to-ceiling window that lets London in. Its flatiron shape means everyone gets lots of light, plus there’s a fantastic 8th-floor terrace bar with London Eye views. The blocks nearby are slightly sleepy, but there’s much choice within a 5-min.walk in most directions. It sells out frequently because it’s worth it.
