Antolins apartment is very nice. Small, but has everything you need, especially if you plan on going out a lot. The only things worth noting are that you don't have your own toilet but that was a minor inconvenience, as the shared one was very clean. And the apartment is on the 7th floor, which you should consider. During my stay it also smelled like smoke, which might have been the previous guest. The apartment is very close to a Metro station which makes things easier. The Seine is also pretty close so you can easily do a river walk.
Antolin was a very nice host, communicated very well and was helpful with the check in. He even carried my luggage up to the 7th floor, which was very kind!
I'd recommend this apartment to everyone who wants to enjoy a nice stay in Paris!
