We spent 4 days in London, and we were very pleased with our accommodation, indeed. Firstly, it was very close to the city centre, so we didn't have problem with the traffic.
What is more, the inside of the flat and our host all were extremely friendly. Our bedroom was comfortable, we could always take a big rest at the end of our days. We also liked the bathroom.
All in all, we are happy that we had such a good experience with this accomodation!
