Dear against All Odds
We stayed in the 'Jurys Inn' on pentonville road, Islington road when my dd attended Central Easter school a few years ago and walked to Central each day.
There are student studio rooms in Aldgate East which is just a short tube ride to Central. The top floor rooms are rented out to the public. Assam Place, Commercial road, Aldgate East.
Have Central not given you a list of possibilities?
