As Arjan wasn't there when we arrived we got our keys from the lovely guy in the vegetable shop across the street. We wanted to meet Arjan before we left the house so we waited for him to come home. During the wait my better half (and dog) Tala and Lieverd got to know each other and already came along...when Arjan came home we got to know a person just as amazing as his dog is.
"Be the person your dog thinks you are."
Arjan was the best host we could wish for (even my extra-shy dog was okay with him being around) and we would 10/10 recommend his place for an amsterdam stay for people that like to get to know their hosts (also if you don't like to be in too close contact to Arjan, as I read in some of the comments, you can just close the door and/or tell him; but as he is very lovely I don't think you'll need to). Also his lullaby for Lieverd might be stuck in my head forever. Tala gets her lullabies too now every evening .
We also met the cleaning lady, who was very sweet too .
Thank you for everything, Arjan. We'll for sure be back.
To put it in a nutshell: sweet dog, lovely host, lovely location, lullabies.
