Lovely place, comfortable for 6, though better suited for 5. We arrived later than Charlotte expected but she left instructions for us to get the keys and how to get into the apartment, after we figured out ourselves from the reception which floor she stays in.
We had 6 big luggages, it was quite difficult to bring them up and down 4 storeys without a lift, so that should be a factor to consider if you have heavy and bulky luggages.
