Although I didn't get the chance to personally meet Arnie (he was away for a job), Arnie was extremely helpful throughout my entire stay. He responded quickly to my inquiry, provided great directions and advice, and even made sure I had arrived safely to his flat. (During my stay, I stayed with his flatmate Alissa, who was extremely welcoming and a great person to talk to! Unfortunately, I believe she is leaving very soon to another country.) His flat is spacious and cozy and it is conveniently located to both a tube stop and a grocery store; it also has a fantastic view of London! All in all, I would definitely recommend Arnie to anyone thinking about visiting London!
