I had a great stay in Inge's loft apartment. The whole house is very stylish, with original artwork on the walls, and Inge is a friendly and interesting host.
The location is excellent for getting to central London quickly, and nearby Chiswick offers much by way of great shopping, lovely boutiques, great restaurants, and lovely walks by the river and in Chiswick Park. The St Peter's Square is really lovely, and there are some great pubs within easy walking distance of the property. I can also highly recommend Artisan coffee on the way to Stamford Brook station!
The only drawback to be aware of is the proximity of the A4, especially if you are a light sleeper. I would suggest investing in some earplugs for sleeping, and some noise-cancelling headphones if you want to watch tv with the windows open. Otherwise, the apartment has pretty much everything you would need for a comfortable stay (even a walk-in wardrobe, with storage for suitcases, etc.!)
