I was doing exams the week that I stayed with Tatjana and Kate. I chose their place because it was reviewed as having a comfortable bed and being quiet. It lived up to those expectations, and more. Every night there, I slept well, and I was able to work productively in the room. I was never disturbed.
When I did chat to Tatjana and Kate, they were warm and we had interesting conversations.
I would highly recommend for business people who want to be productive while in London.
Also, the Parsons Green area is nice in a suburban kind of way, while being very close to central London. The tube station is indeed really near, 4 minute walk. You have a Sainsbury's local around the same distance which is handy, and then Fulham Broadway about 10 mins walk for more shops/pubs/cinema.
Overall, excellent!
