We rented the flat for a long weekend and very really happy with it!
The location is great, rue Moufftard is full of shops, cafes, restaurants, bars, some of which are really amazing. And you can walk to Notre Dame in like 10 minutes (It's a very nice walk!)
The flat is very bright, spacious and cozy, perfect for a couple.
We haven't actually met the host, but she was very helpful and we received the keys and found the flat with no problems.
Highly recommend!
