We never got the chance to meet Desiré but her mother was super lovely ! Everything was prepared to welcome us, and her mom was always ready to help.
However, we noticed that a few things were missing : no shutters or even curtains on the bedroom, no shower gel (bring yours), no table to eat just two chairs in the kitchen, it was pretty noisy at night (so prepare earplugs just in case).
Despite all the lovely attentions, the location (30 min from the major activities) and the easy arrival and departure organisation, we thought it was a bit overpriced. We still would recommend it for you next trip in London !
