I stayed at Hugh's place for around four weeks, and really enjoyed the experience. The apartment is exactly as you would expect from the pictures---comfortable to sit in the living room (and watch an excellent projection tv), idyllic in the two-level garden which was lush even during a very hot month, making use of a well equipped kitchen, and enjoying the calm and cooler temperatures of the garden level bathroom and bedroom. The house has been lovingly remodeled and has lots of nice architectural and design touches.
The area was new to me and is a really great place to be based. You have both the feeling of living in a neighborhood (just wander around a couple of blocks away from KX), as well as the proximity of both the wonderful development around the canal and coal drop yards behind KX and leading back towards KX, the walking access to Exmouth Market (Clerkenwell) and Islington High st., and of course the easy proximity to the gateways of KX, St Pancras, and Euston.
Hugh was very easy to communicate with, and ready with advice and tips. I would stay again.
