Catherina was a very obliging and helpful host and her apartment is charming. The location is superb for tourists, with many of the major attractions within walking distance (Louvre, Tuilleries Garden, Notre Dame, Pantheon). The metro (Odeon station) is only a few minutes walk from the front door. Saint Germain is blessed with many restaurants and the evening ambience (street musicians, open air dining) is great. Though tiny, the studio apartment is extremely well equipped and functional. We were able to cook an occasional meal and to do some laundry. Catherina did warn us of the two levels of stairs we needed to climb in case that was a problem for us, but apart from initially getting luggage up, and then down when we left, it was fine. Catherina was very accessible, both while making arrangements and during our stay, going out of her way to assist and make us welcome. She was very, very understanding when our arrival was unexpectedly delayed, and we had difficulty with phone reception, despite us keeping her waiting. And her welcome treat of a tart from a local bakery was delightful. There are many local bakeries and other food providores nearby, as well as a small supermarket. We did find the wifi connection a little fickle. As a small upstairs studio, ventilation is limited and it did retain the heat so it can be a little uncomfortable in warm weather.
