It's too far to walk to the address you gave from Paddington Station, you could get a cab - it'll be about a 10 min drive. Or get a tube to tottenham court road and walk from there.
Put the address into google maps to find the walking route.

I think you mean Rathbone Place, which is a tiny side street, a short walk from Tottenham Court Road tube station. From Paddington, take the Bakerloo Line to Oxford Circus and then change to the Central Line for Tottenham Court Road. There are a whole bunch of exits from TCR station - you want Oxford Street north side.

The whole trip, including walking and waiting, shouldn't take more than about 25 minutes. A cab from Paddington may be quicker, but you stand a fair chance of spending a long time waiting in line and then another long wait, this time with the meter running, stuck in traffic in Oxford Street.
