Christian is very helpful and attentive. Self-check-in is very easy and not a problem. The only slightly negative thing to mention is that the mattress of the bed is rather old/thin so you can feel the coil springs in it. And the flat isn't very well connected to the tube system. But if you're visiting as a tourist and got time that's ok :) you can walk the 20mins to London eye and then are better connected there.
