Prince of Wales Terrace is a street in Kensington, in the Royal Borough of Kensington and Chelsea.
One notable building is the Clearlake Hotel. 
Another building notable enough to be mentioned in Wikipedia is number 13, which became Stanton Coit House around 1953 in memory of Stanton Coit, who died in 1944. The purchaser, the Ethical Church, which Mr Coit had founded in the 1890s, reverted its name to the West London Ethical Society and rejoined the Ethical Union.
