Gusto is easy to miss but it is near the colourful Zizzi restaurant so you can't miss it. Its quite tiny but not uncomfortable. Having booked on line be sure to read the instructions about hair length. My hair at the sides was below ears but towards the back it was slightly longer and this was classed as shoulder length. Raluca told me this would be an extra £5. I was happy to pay but unfortunately I did not have my card on me but offered cash which they do not accept. A client paid.
