hotel in London with 2 adults and 3 children?

[notahappycamper]

So can anyone recommend a hotel where we can all stay in 1 room? Or will I have to pay for 2 rooms?
Or should I look at an aparthotel or whatever they are called?
I have been searching but not getting very far. Except I know I dont want to stay in a youth hostel.
TIA

we found places on the roomfor5.co.uk website recommended by another MNetter. as your kids get older you do have to have 2 rooms unfortunately. we stayed in a premier inn and got interconnecting rooms but still can work out more expensive as soon as the youngest is out of cot!
