We had a great stay at Sophie's!
She was away for the weekend, so we didn't meet. But she gave us all the important information and kept in contact to make sure everything went well! Great description of the self check-in and a very beautiful and super clean apartment. Also my friend forgot her drink bottle and Sophie send it back to her (thanks again!!).
The apartment is an a great area with many supermarkets, cafes, etc. close by and a short walk to the tube station!
