Oliver Plaza is great! great location (near Earl's Court station, most of the attractions 30 minutes far by tube and around 45 minutes from Heathrow using the Picadilly line). The continental breakfast is ok (sliced bread, butter, marmelades, croissants), juice, coffe and tea, iogurt and cereals! Paying a little bit more, you can have english breakfast. Staff is super nice! The only problem I had was a noise of some kind of enginee running at night and making the room vibrate (it was not the air conditioning of my room because I let powered off - however, I don't know if it was of the side door)
