We had a wonderful stay here.
Since the moment we made the reservation, Marc has always been available to answer questions. Even though he said he wouldn't be there when we arrived, he was! He came to see that everything was in order, and again iterated he will be available for any questions or concerns.
The apartment is a very small one, on the 6th (if you start from the ground floor), or 7th in American terms. It is a climb for sure, but we treated it as some much needed exercise :). Small bathroom and a very tiny kitchen, but it has everything you need, including a small yet spacious refrigerator. There is also a tv with French cable, and a small table for two. When you open the window, it looks over some rooftops and down into the courtyard.
I do have to say the bed is very comfortable, and the comforter is super warm. Pillows are perfect... all for a good night's sleep.
What's best about this place is the location. It is in the heart of St Germain. You just can't find a better place to be. If you don't mind smaller spaces, I highly recommend this apartment, because I certainly will be back here each time I'm in Paris.
