Julien is the best. My flight was canceled without any notice at the last minute late on a Friday night. Thankfully, he responded quickly and I was able to have a place to stay.
I also had some issues with transportation the next day and he went out of his way to pick me up.
On top of that, he then helped me deal with the airline company that wanted to cancel my flight once again.
Basically, had it not been for him, my whole weekend would have been a big awful messy disaster, but he saved the day and made my stay nicer than possible.
Also, he is a worldly and smart man who can talk about any topic, so we shared many hours of deep interesting conversations and I learned a lot.
He is the nicest person and the best host I've stayed so far. I couldn't recommend him more. I will definitely stay at his place again next time I go back to Lisbon.
