I've been travelling with Air BnB since 2010, and Sophie gets my highest recommendation. She is cheerful, knowledgeable, and helpful -- and I was *so* lucky to find her place on short notice when my other lodging plans fell through. The flat itselt is very comfortable and clean, well located, and in walking distance to everything. Everything in the flat works as it should, and Sophie carefully enforces the "No Smoking" rule -- which I really appreciate.
