London Marriott Hotel County Hall

The honest review

London family hotel selection usually comes down to a tradeoff: you can be central (expensive, cramped) or you can have space (suburban, inconvenient). The Marriott County Hall finds a third path by occupying the former London County Council headquarters directly on the South Bank — a building so central that the London Eye is literally in front of the entrance and the Thames path to the Tate Modern runs past the door.

For families, the South Bank location is as good as London gets. The London Aquarium is in the same building. LEGOLAND Express runs from Waterloo Station three minutes away. The Imperial War Museum, National Theatre, Tate Modern, and Borough Market are all walkable. You don't need the Tube most mornings, which is itself a significant quality-of-life upgrade with kids.

The hotel has an indoor pool — not glamorous, but London hotels without pools are the norm, so this matters. Family rooms fit two adults and up to two children comfortably, though they're not enormous by American standards. The building is historic (1922 Grade II listed), meaning some standard rooms are compact; booking a family room or junior suite specifically matters here.

Where it loses points: the price is genuinely high even by London standards, the kid amenities are hotel-standard rather than family-resort dedicated, and the restaurant is fine but the South Bank has so many excellent options within a five-minute walk that you'll probably eat out most nights anyway. The familyFactor score of 78 reflects excellent location and pool access against average-for-the-category kids programming. If your family trip is about seeing London rather than a resort experience, this is the right choice.
