Karin and Oli's place is beautifully appointed and was perfect for our family's stay in London. We'll definitely stay again.
Having lived in London previously, we can confidently say that their apartment is huge by London standards. There was lots of room for our baby son to roll around on the floor, and enough separation between the rooms that we could put him down to sleep in one of the rooms and still have friends over for dinner.
The location is excellent. It's a stone's throw to the tube and barely a stroll until you're walking along the Thames and popping in and out of historic pubs.
Karin and Oli were also the perfect hosts. Not only are they delightful people, but they managed the delicate balance of being on-hand when we needed them (e.g. fix the dishwasher), but not at all obtrusive.
