We spent 3 days in London.
We were welcomed warmly. Despite of our early arrival, Julie told us to let our bags as our room was not ready yet and let us eat in the living room. The appartement is cosy and it's pretty easy to feel like home.
Downstairs, the bedroom is really nice for two people, a soft bed, many storages, towels, little bin and appartement's rules (+ tips). Bathroom and toilet (downstairs too) are spacious and very clean !

Moreover the appartement is really at 5 minutes of the New Cross Gate Station which is served by the Overground (2 stops for the Jubilee Line/6 for the Hammersmith and District Lines) and many coaches going to the center of London.
To sum up, we were really satisfied of our journey. Julie is a great host, she is discreet but very helpful if you ask.
Thanks again to her !
