I stayed with Mark and Jorge ahead of a business trip in London and had a fantastic time. The apartment was gorgeous, and the deck is exactly as it is pictured - an escape from busy London. Mark was away when I arrived, and went above and beyond to make sure that I was let in when I showed up in the middle of the night.
The apartment was so lovely that I ended up spending half the morning there one day without realizing it, until I told myself I had to get up and go explore. I didn't venture too far - I loved just wandering through Hackney and Shoreditch, and ended up on Columbia Road every day for some reason or another. The location was perfect for me and I even did a long walk down to the Thames one afternoon.
Mark also was very responsive before I arrived (I tend to ask a lot of questions) and great about recommendations once there. My last night there he directed me to a nice rooftop for dinner. Would absolutely stay there again and recommend to anyone!
