Location, location, location! In the heart of Soho with bars, restaurants, theatres all around. 2 min walk to Chinatown, 5 min walk to the Piccadilly Circus and underground station (about 35 min tube ride to Heathrow), 15 min walk to Trafalgar Square.
The apartment is a typical studio, about 20 m2, no frills, but clean and comfortable. It's a 3rd story walk up with windows opening to the courtyard which hosts a bar. It's noisy every night until around 11pm (no music, just lively conversation) if you have the windows open. It didn't bother us, it actually added to the ambiance of being in the heart of a lively neighborhood.
Nick was very easy to communicate with and responded promptly to all our questions. I recommend this place for any visitor, especially if this is your first time in London and you want to be close to many of the city's attractions.
