too heavy and large

Purchased for a stay in London, I return the car I do not see how to use it by visiting. Too heavy, too big and difficult to replicate in his house so I can not imagine the street. Too bad because it is very detailed but really about central London. The area where my b & b is not over while in zone 2 of public transport which are numbered up to 9. I hope to find a model more suited there.
