The Problem
As a rapidly growing property management company overseeing 250+ apartments across Spain, the operations team faced critical scaling challenges. Guest check-ins consumed enormous staff time with lengthy manual communications and multiple links. Spain's strict tourist regulations required manual collection and reporting of guest data to authorities - a time-consuming process that raised concerns about handling sensitive information. Their existing systems were rigid and couldn't adapt to their operational needs. Guest complaints about recurring issues were affecting reviews, and the team lacked bandwidth to offer revenue-generating add-on services. With ambitious growth plans ahead, they needed a solution to centralize operations, automate repetitive tasks, and deliver premium guest experiences - without hiring more people.
The Solution
The company implemented Enso's flexible automation platform, which stood out for its "if this, then that" logic that adapted to their unique workflows. At the core of their transformation were two key features: the Boarding Pass and unified inbox with AI. The Boarding Pass consolidated all guest information, access instructions, and check-in requirements into one convenient digital experience, eliminating lengthy text messages and multiple links. Through Enso's integration with Checkin, guest data now flows automatically to Spanish authorities without the team handling sensitive information directly. The AI-powered unified inbox enabled faster, more personalized guest communications. This freed up significant time, allowing the team to launch premium add-on services like paid early check-ins, baby cribs, and tours.

How WAOU Rentals Transformed Guest Management Operations with Enso Connect
WAOU Rentals was facing a common dilemma among fast-growing vacation rental professionals: how to scale efficiently while maintaining a premium guest experiences across 250+ apartments.
Manual check-ins, rigid compliance reporting, and inflexible systems were holding them back from their ambitious expansion plans and preventing them from delivering the premium experience their brand promised.
Finding the Perfect Match: Why Enso Connect
When the company management and operations team discovered Enso Connect, they recognized it as the perfect match for their needs.
"After seeing what Enso could do and all the problems we were facing, I immediately knew this was a perfect match," recalls the Deputy Director of Operations.
Unlike other platforms they had evaluated, Enso offered the flexibility they required through intuitive "if this, then that" automation logic. Other systems were too rigid, but Enso could adapt to their specific workflows.
They were also specifically looking to integrate artificial intelligence into their guest communications, and Enso's AI-powered inbox delivered exactly that capability.

The Enso Solution: Boarding Pass & AI Communication
Two features transformed WAOU Rentals' entire operation: the Boarding Pass and the AI-powered unified inbox.
Streamlined Check-ins with the Boarding Pass
The Boarding Pass streamlined their guest check-in process by consolidating all information, access instructions, and requirements into one seamless digital experience.
No more lengthy texts. No more scattered links. Everything guests needed is now in one convenient place, and the team can verify completion with a single glance.
Automated Compliance Reporting
The compliance challenge that had consumed hours of manual work each week was solved through Enso's integration with Chekin.
Guest information now flows automatically to Spanish authorities without the WAOU team ever handling sensitive data. They maintain full compliance without the administrative burden.
Faster, Personalized Guest Communication
The AI-powered unified inbox enabled faster, more personalized guest communication that made every interaction feel human and attentive, even as they scaled.
Guests get answers immediately, and the team can respond to requests in a more timely manner, creating the premium experience WAOU Rentals had always aspired to deliver.

Seamless Integration with Avantio PMS
Thanks to Enso Connect's onboarding team, the integration with their Avantio property management system was smooth and efficient.
The setup was much smoother than expected, allowing WAOU Rentals to get up and running quickly without disrupting their operations.

Exceptional Support When It Matters
"I only have good words for the Enso team," says Frank de la Fuente. "They were incredibly supportive throughout the entire process - always available and quick to solve any issues."
WAOU Rentals works closely with their customer success representative Felipe.
"We don't have many issues, but when we do, we talk to Felipe or Nico and they solve everything immediately."
The Features That Drive Daily Operations
Two features have become essential to WAOU Rentals' daily operations: the unified inbox and the Boarding Pass guest app.
The Boarding Pass helps them deliver the entire guest experience in one place and control that everything is okay for each arrival.
The unified inbox with Enso AI is an amazing tool that allows them to respond more immediately and give guests what they're asking for in a more timely manner.
These features are the foundation of how WAOU Rentals operates at scale.
