We spent a few days in Glyn's appartment and it was really great. It is well located and it is easy to reach all the main places of London. The street is quiet and you can find some good restaurants nearby.
Just one remark, from our point of view, the appartment is perfect for 2 or 3 people, a bit short for 4. But it was still a really good stay in London.
I highly recommend it!
