Chokri is a great host and his La Marais apartment is a great spot to see all that Paris has to offer. While we walked everywhere, despite a bit of rain, the metro, taxi, and Uber are all easily accessible to get you where you want to go. Chokri was very responsive when we had questions and offered lots of suggestions on things to see while in Paris.
This apartment is quaint and cute, but has all the comforts of home so you don't feel like you need to rush out to a restaurant for every meal. Go to a market, many are very nearby, and buy some good French produce, pastries, and cheese to make yourself a meal and sit on the balcony to people watch. When you do venture out you are only a short walk to almost everything you would want to see while in Paris.
We will certainly consider this place again if we find ourselves in Paris again.
