My stay at Marie-Therese's place was almost perfect. When I arrived the instructions were very clear and I had no problem reaching the place.
The place is very central and reaching the major interesting places of the center is easy even on foot. The flat is beatiful and functional and as sunny as the pictures promise.
Communication with the Marie-Therese was flawless, she answered quickly all my questions.
The only mishap was when I went to bed and found some hair on the bedsheet. Usually this would be a bad sign but given the other reviews and the fact that the place was otherwise extremely clean I imagine this is a non-recurring event.
