Sandy's place is outstanding. Super clean, amazing amenities, amazing communication, parking (which is RARE in London), and top it off with only a 2 minute walk to the train station. If you take the Express train (runs a couple times an hour) you can get to Waterloo station, downtown London in about 15 minutes (Nice!). There are trains every few minutes and even if you get a 'local', you still get downtown in around 25 minutes.
Sandy's place was absolutely perfect for us: lots of space, beds for everyone, trampoline and swings for the kids. It's decorated very nicely and was a great home for visiting London. We would definitely come back to Sandy's place.
