If you want to stay in an apartment above the center of what would probably be Oxford Street in London this is a good place.
The location is very central, above commercial property, it was a quiet building in terms of noise from within. It’s on the 4th floor so the amount of noise coming from the high street isn’t ba, but it does mean there can be some random noises late at night (people screaming / laughing) but nothing that kept us our our 3 year old son awake.
The apartment itself has a nice styles (as seen in the photos). The kitchen is really just a kitchenette, good for breakfast, but I wouldn’t use it to cook a meal for 4 people (which the place can easily accommodate with the two bedrooms). The bedrooms are on opposite sides of the apartment with the living room in between, I like this because it gives you more privacy. There are blackout blinds in the bedrooms which can keep the light out completely if you like.
