I really enjoyed my stay! It was nice and quiet, yet right in the center of the city. I only stayed two nights so I couldn't get to know Juan very well (too bad, he was so mellow and cool!). He was kind enough to let me and my travel mate leave our bags just past checkout so we could tour the city while we waited for check in at our next hostel. We also had space in the fridge, to store our meals for the whole stay, what a great luxury.
Overall I would recommend Juan's place to anyone looking to settle in for a stay in Paris.
