I stayed at Adam's for around 2 months and it was an incredibly pleasant experience. The check-in experience was punctual and welcoming (he knew I loved chocolate bounty bars), and he was always very responsive replying to my texts and catering to sudden situations. For example, I had to leave a little early due to a new job opportunity outside of London, but Adam was also very considerate around the quick change in circumstance and made the rest of my stay a pleasure.
Would definitely recommend, and I'll be reaching out again whenever I'm back in London.
