Everything about Thorsten's place was great - price, location, cleanliness. He's quick to communicate and provided very clear instructions on how to check yourself in. The location was amazing and although further from more tourist-y attractions, it was very safe and easy to get around. The flat is also a 10 minute walk from Chatelet-Les Halles so commuting from either airport is very easy. I highly recommend booking a stay here, don't hesitate.
