Although we didn’t see Oliver, Marcus was more than enough of a host being talkative and friendly. Their aparment was prettily decorated and looked as good as it did in the photos. They had even got me me a birthday card which was super cute and unexpected.
Overall it was a great experience that I would recommend to others!
P.S. You should definitely ask them about what to see in London they are very knowledgable about art & culture and gave great recommendations!
