Soo's place is amazing and the hospitality and communication is WONDERFUL. The location is great - right next to Tower Hill, Tower Bridge, London Tower, St. Katherine's Docks...there are plenty of places to eat within walking distance, several pubs within walking distance, a Starbucks (if that's your thing), small coffee shops...basically everything you need to have a solid home-base while staying in London.
Now, I am the type that generally only reads the bad reviews before deciding to purchase, not the good reviews.
There really is nothing BAD about this place. But there are a couple things you'll want to keep in mind when packing. First off, there is no AC. This is probably perfectly fine most times of the year and completely normal for England, but when I visited there was a heatwave, and there were no fans in the rooms, which made for some somewhat uncomfortable nights. Also, you will get one towel and be expected to use it for the duration of a week. If you expect to have more than one, or a hand towel, or face towel, it might be best to just pack one.
So that's that - I wouldn't hesitate even a second to stay here again (I'd just make sure to pack a couple face towels and maybe even a small portable fan, just in case). Soo is the most gracious and wonderful host, the house is wonderful, the location perfect.
