Simon's flat is amazing and when I come back to Paris, I would def try to stay there again! Everything is as described, the location is central (easy to get to from gare du nord too) and Simon was very helpful with ad hoc questions we had (we even did laundry). He arranged for us to have an early check in and a late check out, so we could enjoy Paris as much as possible. Very well organized, in general very accommodating and with clear instructions of how to use everything in the house. The flat is actually bigger than it looks in the pictures! I think it's good value for money.
