A fantastic place. Immaculately clean, well-appointed and very comfortable--and an absolutely stellar location.
Very peaceful, too, despite being right in the centre of everything a stone's throw from Piccadilly Circus, on a calm & quiet street and in a solid, secure, well-maintained building.
Check-in & -out was extremely straightforward via the lock-box.
I wouldn't hesitate to recommend, or to stay again--a lovely, clean flat within short walking distance of London's main attractions & theatres!
