Great central location, and a very friendly host who will do everything to make your stay comfortable.
Though I would recommend this flat for a shorter stay, we encountered some issues that made a long-term remote work stay for us not possible and had to leave early. The WiFi was slow and spotty at best, and while Mary tried to troubleshoot with the service provider, we ultimately weren't able to get things working.
Note that the proximity to public transportation also means that the second bedroom can get quite loud, the Thameslink train runs just outside the window. The master bedroom remains quiet, though.
Living room is spacious, and the kitchen does supply basic cooking necessities. Keep in mind that this is someone's house, so the host's belongings are present throughout the house. Not a problem for a short stay, of course.
