The good:
1. The view is the best I have ever seen from an apartment in Paris.
2. Guillaume himself is a very nice man who is easy to talk to.
3. very modern amenities like Coffee maker and good entertainment/WiFi speed.
The Neutral:
1. The space is very small. about what I expected from the listing, but It would be a real press for more than one person.
2. There is an elevator but it stops on 6 and the apartment is on 8, so any bags you bring have to be portable up a staircase.
The less good:
1. When I booked, the listing said it had air-conditioning. It doesn't. If it is a hot week, you will be hot.
2. Guest ready is a big, fairly impersonal service that doesn't respond to problems very well and certainly doesn't work weekends. (though both the check-in people were really sweet)
3. It is between two train stations, so life on the street outside can sometimes be a bit more vigorous than you might want to listen to.
