We really enjoyed our stay at Mario's and John's house. They are brilliant hosts. They worked every detail in the house to make you comfortable through your stay.
The studio is very nice, the garden is beautiful and the litlle square in front of the house "tres sympa". Although there is no tube nearby there is a nice walk along the canal to Angel tube worth walking.
We strongly recommend it if you want to spend time in London.
