Operations advisor for short-term, mid-term and flex living operators

Scale units.Not headcount.Not chaos.

For operators with 50 to 1,000 furnished units. I fix the operations that break as you grow, and turn 30+ night stays into a B2B channel.

30 minutes on your portfolio. No pitch deck. If I can't help, I'll say so.

Sound familiar?

“Every new building means more hires.”

Headcount grows with units. Margin per unit doesn't.

“Our operations live in spreadsheets and in two people's heads.”

PMS, channel manager, cleaning and owner reporting don't talk to each other, so your team fills the gaps by hand.

“We depend on Airbnb and Booking.”

Mid-term guests probably book with you already. Nobody is selling to the companies, universities and relocation firms that send them.

Built for operators, not individual hosts.

For

  • Short-term, mid-term and flex living operators with 50 to 1,000 units
  • Rental and travel startups that already process bookings or leases

Not for

  • Fewer than 30 units
  • Hotels
  • Companies looking for a report to file away

Three ways to start

Fixed scope, a result you can measure. Most operators start with the diagnostic.

After a project, I can stay on as fractional COO to lead execution, a few days a month.

We agree scope and fees after a first call.

How I work

The goal isn't a better strategy deck. It's an operation that needs fewer people per unit.

  1. 1

    Map

    Cost, hours and handoffs per unit. Where the work really goes.

  2. 2

    Design

    Processes, owners, systems and a few KPIs: units per person, occupancy, length of stay, turnover cost.

  3. 3

    Build

    PMS workflows, automations and AI agents with human approval, SOPs. Built with your team.

  4. 4

    Hand over

    Your team runs it. I step back.

The goal is that you stop needing me.

Questions

Is this right for my size?

It works best from 50 to 1,000 units. Under 50, a few fixed processes usually beat a project, and I'll tell you which ones on the call.

Do you replace my ops lead?

No. I build the system with your team and hand it to your ops lead. If you don't have one yet, I help you define and hire the role.

Do I need to change my PMS?

Usually not. I work with the tools you have and suggest changes only when a process needs them.

Short-term, mid-term or flex living?

All three. Most operators I talk to run a mix, and the work is deciding which unit goes where.

Where do you work?

US and Spain, in English and Spanish. Based between Miami and Madrid.

How do we start?

A 30-minute call about your portfolio. If there's a fit, the usual first step is the Operations Diagnostic.

Oscar Rubio Martín speaking on stage

Operator first.

I didn't start as a consultant. I started by building and running rental and relocation businesses.

I've built teams across Latin America, Europe and the US, fixed broken processes, sold to companies and universities, launched software and opened operations in five countries.

Today I work with a few furnished rental operators and rental startups at a time, in the US and Spain.
