A few weeks ago I found myself with a free afternoon so thought I'd give this place a try. Messaged asking if anyone was available in about 40 mins, yes was the reply, so booked.
I arrived outside on time and messaged, no reply. After 10 mins I messaged again, then after 20, still no replies. At 30 minutes I gave up and left.
After about 45 minutes I got a "I'm ready now"... too late. I'm guessing someone stole the booking, but it's hardly a walk-in kind of place. Just poor organisation really. Will maybe try again one day.
