Nice visit, but it's in english. I'm used to speak english everyday in my work with customers, I understand therm and they understand me.
But a visit is a different level of english, much more words, vocabulary, technic words...so if someone is not perfectly fluent it's always an effort to focus and understand, in particular in the street. And moreover, the guide was speaking with a VERY VERY high speed !!!
I asked him to do it a little bit slower for non english speaking people. He answered me that he had difficulties to adjust and finally did not make any change, effort or whatever to help me understanding better.
Very disappointing, i quitted the visit before the end and was angry bout that.
SO DON'T DO THIS TOUR IF YOU DON'T HAVE A PERFECT LEVEL OF ENGLISH OR IF YOU ARE NOT AN ENGLISH OR US NATIVE PEOPLE !!!
