My partner, my mother and I stayed at Simon's for 5 nights over the 2014/15 New Year and we couldn't have been happier. We spent long days out sightseeing and it was a pleasure coming home at the end of each day - it is an immaculately kept, warm, comfortable apartment with a nice feeling about the place. Our arrival was handled seamlessly and a helpful pack of information was left for us.
The neighbourhood is great with bakeries and cafés close by and it is a stone's throw from the Luxembourg Gardens with the Pantheon a short walk beyond them. For those who enjoy walking, many things are a walkable distance. There are also two metro stations a 1 minute walk away, making getting around and home again very easy.
Truly, our experience of Paris was so positive that we all fell a little bit in love with the place and the apartment was a big part of that - and Simon as our host was a big part of *that*. While we sadly didn't get to meet him, through spending time in his space and my interactions with him it's something we all agree we would like to do one day! Simon was responsive, clear, generous and kind.
If you are looking for a place to stay in Paris, make it here - you won't be disappointed.
