I can not recommend Chloe and Helene's apartment enough. Chloe was on vacation while I was here but Helen was beyond amazing. It was very cold in Paris while I visited and so Helene hosted a raclette night (basically delicious cheese melted over potatoes with all kinds of meats and wine) and I got to meet several of her friends and it was such a fun evening.
I also had never been to Orsay despite several trips to Paris and she took me through the museum (which was so cool to get a tour from an art history major).
Beyond that she's just super cool and we enjoyed some nice evening chats together. I would definitely stay here again!
