John was communicative and allowed you to feel you had your own space. It's pretty much a private studio connected to the rest of the house. The space is relatively small for a studio, but still more space than a regular private room. It's about a 20 minute walk to the Piccadilly line which takes you right into the heart of London. Also, the garden is gorgeous, I wanted to floric in it but didn't have the confidence to ask.
One warning I would have is that if you have limited mobility the stairs could be a tad tricky, as it's quite spindally though not particurlarly long.
