The Black & White G&G is a little hard to find (we walked right past it twice, although not helped by the fact it was dark!), and would perhaps benefit from a bigger sign outside, if possible. That's the only negative point I can make, the rest of the stay was great; staff were friendly and helpful (even sorted us with a lift to the airport at 4am on a Sunday!), the room was clean, tidy, and looked great, the bathroom was nice and clean, and breakfast each morning was lovely (the freshly made coffee was fantastic!). The area is lively with restaurants and bars, but the hotel isn't so close that you're disturbed by it.
I'd highly recommend the Black & White G&G for anyone having a city break, it's in a great location and is a lovely place!
