The phone that rang at eleven at night

Seven minutes past eleven at night. Nacho's phone buzzed on the nightstand, on top of the book he hadn't got past three pages of. He picked it up without turning on the light, so as not to wake his wife.

WhatsApp. A number starting with +34 that he didn't have saved. "Hi, sorry about the hour. We arrive tomorrow, what time can we check in?"

Nacho answered from bed, in the dark: "Good evening. Check-in is from four in the afternoon. Anything you need, I'm here." The check-in time was in the booking email. It was on the website. It was, word for word, in the last forty conversations on his WhatsApp. But he answered anyway, because a guest who asks at eleven at night and gets no reply turns up the next day with a nagging worry.

Nacho runs a guest house, El Encinar, in a village in the Sierra de Francia. Six rooms, a fireplace, views over a valley of chestnut trees. He runs it with his wife and a woman who helps with the cleaning. There's no reception, no shifts, no phone for the house that's different from his own. The house phone is his phone.

The same questions, at any hour

Into that phone came, day in and day out, the same eight or ten questions. What time is check-in. What time you have to leave the room. Whether there's parking. Whether they take dogs. What the wifi password is. Whether there's heating, which in the sierra in January isn't a silly question. How to get there, because the GPS sometimes sends you up a track that isn't the one. Whether breakfast is included.

They asked through WhatsApp, through the website form, through the booking platform's chat. At nine in the morning and at midnight. And Nacho answered them all, one by one, typing out the wifi password for the umpteenth time with two thumbs, from the vegetable garden, from the car, from the dinner table.

He didn't mind helping; he minded that helping had turned into repeating. Because they weren't different questions from different people: they were the same question over and over, wearing a different face. And the house never closed, because the person answering it never closed.

What he asked for and what he needed

Nacho wrote to me —how else— on WhatsApp. He asked for an automatic message, one of those that fire on their own: "Thanks for your message, we'll get back to you as soon as possible." He'd seen others had one and thought it would get the phone off his back for a while.

But a "we'll get back to you as soon as possible" answers nothing. The guest who asks what time they can check in still doesn't know what time they can check in; they only know that someone, at some point, will tell them. What Nacho needed wasn't a message that stalled. It was something that actually answered, with his house's information —his check-in time, his password, his way of getting there— at eleven at night, without him. And that, when the question was one of the real ones, handed it to him.

How it works, no smoke

What we built isn't a robot pretending to be Nacho. It's an assistant that knows what Nacho already knows: the same answers he'd spent two years typing out. When a guest writes on WhatsApp asking the check-in time, it answers right away, with El Encinar's time and in the house's tone. The wifi password, the parking, the dogs, how to get there without trusting the GPS: all of that it answers on its own, at any hour.

The important part is what it does when it doesn't know. If someone asks something that isn't in its information —whether they can arrive at two in the morning, whether it'll keep a cake for a birthday— it doesn't make it up. It says it's passing that to Nacho, and it passes it, flagged, for him to see. It doesn't guess; it tells what it knows from what it doesn't.

And here we have to be honest: this isn't Nacho's hospitality. The guest who wants to chat about the area, to be recommended a walk or a restaurant, Nacho looks after, as always, because that's half the point of a guest house. The assistant isn't there to replace that part. It's there so Nacho doesn't have to type out the wifi password for the three-hundredth time at eleven at night.

What changed

Most of the questions now get answered before Nacho even gets to see them. Someone asks the check-in time at midnight and receives the check-in time at midnight, not a "we'll let you know". When Nacho checks his phone in the morning, he doesn't have ten messages to answer: he has the two or three that were truly for him, already separated from the rest.

Something started showing up in the reviews that hadn't before: "they reply straight away", "they sorted everything out for us before we arrived". And Nacho stopped answering from bed. He summed it up like this:

—Now I have dinner with my phone in my pocket. Before, I had dinner with my phone in my hand.

The house phone was his phone

What was happening to Nacho happens to any small business where the company phone is one person's phone: the guest house, the clinic, the workshop, the shop. The same questions, always the same, at all hours, always to the same person. They aren't hard questions. They're repeated questions, which is different.

We didn't have to set up a call centre or pretend there's a team behind it that doesn't exist. We had to gather the answers Nacho already gave and put them where the guest asks, at the hour they ask. So that what can be answered on its own is answered on its own, and only what truly needs his attention reaches Nacho.

Because a six-room house doesn't need one fewer guest or a worse answer. It needs its owner to be able to have dinner without his phone in his hand, and the person asking at eleven at night to know what time they can check in.
