My stay at Viviane was very well! The room is exactly like the photos, the house is beautiful and the bloc is very calm. I slept as a baby! They are buses in 2 minutes and the subway is accessible to feet or with buses. The center (Oxford Circus, south kensington, etc) is close to the house, it's very fast with the public transports. I am satisfied to have spent my stay at Viviane.
Thank you Viviane for your reception and your kindness.
