We enjoyed staying at Ariels place. it is very cosy parisien appartement with nice view. it's not big but that's paris, it was correct for two people. It was perfectly clean and we had everything what we needed.
Location is really good - great neighbourhood, close to the metro, nice canal.
I haven't met Ariel, but I've met his brother. he's a great guy, very helpful.
one negative: bad smell in bathroom from canalisation. it was not agreeable at all to enter bathroom.
