Alix and Richard were both very accommodating to us while we were there. They really put care into the breakfasts they prepare (in the weekends), which were really good, of course. It was nice that they were also the best people to ask when it comes to which way best to get to wherever you want to get in London/around -- very handy! All in all a very comfortable stay -- in their very beautiful and clean apartment.
The only thing to note is that Hackney is a little bit farther away from the main city attractions like The Big Ben etc, so if you meant to stay farther - this is for you. Else, be prepared to spend some time on the bus (a nice journey with a lot of city sights), before you reach town.
