This place is in general a good choice if you go to London on a budget. It is centrally located. There is no underground stop nearby but there are many bus stops with buses going to Piccadilly, Kensington, Notting Hill...
However the place can get dirty and noisy since it is very crowded. The owner doesn’t live there, so the place is basically like a motel with shared kitchen and bathroom, and people can get pretty wild and disrespectful with no regulation from the property.
