The apartment is in a very lively neighborhood with a lot of nice pubs nearby, which is great in the evening. Two tube lines are within walking distance, so it's very convenient for short city trips without a car.
Everything was clean and well equipped, check-in was easy. The only thing to moan about might be the trains which are pretty near and loud, but earplugs are provided and I actually didn't mind the noise, even without the plugs, because I was so tired after the sightseeing :D
