Great host. Awesome communication, very easy to get a hold of, super helpful with tips on restaurants, trains, sights, etc. And very quick to respond. Clapham is a less expensive alternative and I think worth the discount over central London as the Clapham Station train to Victoria and Waterloo stations is just down the road.
Diego will deliver on whatever you need. Its a small, simple and clean, nice apartment that is a way better deal than a hotel, plus some helpful local knowledge while you're at it. Great breakfast spots for a full English or lovely coffee very close by. Would certainly work with Diego (host) again. Very solid.
