Really lovely space, great for the team away day and so nice being in central London! The staff were really helpful in the lead up with all of my questions and really nice and accommodating on the day. It was also great to be able to book lunch in the restaurant and come back to replenished teas and coffees too.
The noise from Covent Garden performers didn't bother us but can imagine it would annoy some people, but there were fans in the room so we didn't always need the windows open.

Great venue, fantastic location, very nice vibe in the room, plenty of space. The guys working there were really helpful and accommodating. Great value - would recommend.
It's right by the Covent Garden performers which is atmospheric but got really noisy at times. On a cold day this would be totally fine as it wasn't a problem with the windows closed, but with them open it was slightly drowning.

Attractive room, bright with big windows. Good facilities and location.
Can get warm in the room with the windows shut, and can get quite loud with windows open.
