The flat is in an excellent location. You really can't do much better if you like the shopping offered on Saint Germain, plus an easy 20 mi mute walk to Notre Dame and the Louvre. The host was a very timely and accurate communicator which isn't always the case with other hosts I've dealt with in the past so that's a big plus. The only reason this isn't a 5 star review is that the apartment did tended to hear up a bit and it was noisy enough on the street that opening the window got a bit noisy. But I would certainly stay here again.
