Elise's place is in a great spot if you don't want to be in the thick of tourists but want to be close enough to hop on a metro to get there.
Everything is within 3 or 4 stops and if you want to keep it local, there are some great little places easily within walking distance too. We are vegan and found a great spot to eat within 5 minutes walk for example.
The flat itself is spacious and exactly as it looks in the pics too. We had a super comfy stay using the sofa bed too, often that isnt the case!
