Ari and José were very quick in responding to all questions I had. Check in was easy once I had found the entrance to their house. You need to pass a white and yellow gate first. It was locked, but when I called José, he arranged for it to be opened right away. The room is nice and big, the mattress very comfy and sheets were super soft. I slept really well. Ari and José are a very nice couple and the dogs are friendly and quiet. The location is excellent if you need to take an early bus from the central de autobusses del Norte. I even walked there with my luggage in the morning (about 10 min). The center (Bells Artes) can be reached directly and quickly by tram (ca 30 min) and the Uber from the Airport was only around 4 USD.
I can recommend their place to everyone who wants to be close to the bus terminal and I would definitely stay with them again.
