Although I never met Guillaume, he always kept in communication and very quick with responses! Great experience!
The Apartment is a cute 6 story walkup, in a perfect location, close to bars/restaurants/sights/Metro... very charming Parisienne feel, perfect for a solo traveller (and my dog!).
Only minor thing of note, is the toilette is shared with the floor (wasn't an issue for me, as I never even saw other neighbours during my stay).
Overall i had a great stay, and would recommend Guillaume and his apartment! Thanks for hosting :)
