The following Text is wirtten from my son, who stayed there for 4 weeks:
I really enjoyed the time at Carlo's Place! He is one of the most nice/funny and helpful persons, that you will meet in London. His flatmates are very nice aswell. They are super funny and like to hangout with you, while giving you a lot of hints, what you could do in your sparetime. The room is a bit small, but it's in London so its fine.
Afterall I had a REALLY good stay at this flat and would love to come back there anytime!
P.S. If you want to be friends with the flatmates just make them some Strawberry-Mojitos and they will love you! :D
