I contacted Renata yesterday by text and it was a good 30 mins before she replied which, to me, indicates that it is her replying rather than someone controlling the bookings for her.
I had intended going around 8:30pm (although didn't specify a time in my text) but work didn't allow so I didn't firm anything up.
I am kind of glad I didn't now having read this as I would have been 3rd in line.
She now has 4 reviews on the from page for London, 2 positive and 2 negative and I am sure that she will feel the effect of that in her bookings.
The only saving grace is that the actual service appears to be a consistent positive.
Today, my plans are going straight to B.
Shame as would like to have met her.
