My wife and I recently spent 4 days in London with our 5 month old baby and Keith was extremely helpful and accommodating. Before our arrival he borrowed a Pack n Play for the baby to sleep in which was very generous.

Upon our arrival we had a number of bags and a friend of Keith's met us and helped us up the stairs. Keith emailed me a couple of times during the stay just to check in and make sure we were doing ok which I found very courteous.

The apartment was exactly as advertised. It is quite a few steps up (4th floor I believe) but once in the apartment it is a great spot. The apartment is on the same block as 2 Tube stations so transit was super easy and you are walking distance to great parks and restaurants.
