London apartments ? for large family

[LargeGlassofRed]

Would love to do London soon with Dc's but not getting anywhere looking for accomodation.
2 bed Apartment would be ideal.
Dc's are 12, 10, 6 and dt's 8 months.

Any help would be great.

Have you considered family rooms at YHA?

Thanks EldonAve, I had a look but children have to be over three.
