Everything was perfect.
First, the flat is located in London’s zone 2, which means that it’s pretty close from everything since all the attraction are in zones 1 and 2. So the SevenDay Oytercard will only cost you 33£. The buses to go to the flat are frequent, there is even one during the night (N137).
Then, the flat itself is quite large, the kitchen is fully equipped, John is ready to provide you all you need. We were 6 and there was 3 double bed and one single bed.
We will keep a very good memory of our journey in London. Thanks.
