As others said, the location on the edge of soho a stones throw from great portland St tube and walkable from the mainline North and west train stations is superb.
The pub opposite mentioned by others was not open whilst we stayed, so can't comment on noise... though this is a ground floor flat so it depends on what is going on upstairs as to how noisy it is... the soundproofing is not amazing... but it was OK (might want to consider ear plugs of you're a light sleeper).
A pleasant walk to Oxford St, China town and the theatres in the west end.
All amenities worked fine. shower was pretty good.
The WiFi wasn't working but Matthew sorted it quickly enough. Matthew was very quick to respond and i would say a great host.
I would recommend. and would look to book again in future.
