The apartment is in a very good neighbourhood, and very conveniently located. It's only a minute away from Le Marche des Enfants Rouges which is very nice. It was, however, a bit difficult to find precisely the gate to enter and to actually enter the house. You will need to be very precise at what time you come in because the host will have to let you in, so it's a bit difficult if you don't have a smart phone with you to arrange the check-in.
The apartment is much smaller than what you would expect from the photos, but it's beautifully renovated and furnished.
The reason I gave a four star instead of a five star was that I didn't find the apartment to be very clean. The wooden floor is old, and if you are used to taking your shoes off inside homes, you'll find that the floor is not clean enough to walk barefoot or without shoes on. We also found fruit flies in the kitchen and someone else's hair on the shower towels and linen, which was a bit unpleasant. But all in all, it's a fantastic experience and I recommend this place to anyone.
