We stayed in Marine's for a long weekend. The flat is probably in the best area you can stay in Paris (I would have given 6 stars to the location if I could have), and is very nice and cosy. Marine was very quick and clear in the communication, and incredibly flexible for our check-in/check-out. Only very minor comment is that we didn't find any shampoo in the bathroom, and had only bath towel per person, so we would have brought some ourselves if we had known before. That wasn't a big issue and we truly enjoyed the stay. We would definitely recommend and stay again at Marine's place if we visit Paris again.
