Elodie’s place is great if you want to explore all the important sights. We pretty much walked everywhere (with a toddler) so its location was more than convenient for us. But staying there with a toddler can be a bit tricky so be prepared (the stairs were the main attraction of the room).
And yes, it seems to be quite humid in there but the dehumidifier is a huge help. We had to empty it quite a lot so it can’t hurt to keep it running while you’re there.
And try the sandwiches from Chez Aline around the corner. Lovely people and great food. Also try the cheese cake from Pâtisserie Emma Duvéré. Heaven!!!
Elodie answered all of our questions and was a big help when we were too stupid to lock the door.
