About Glaser Group

Holiday rental management,
done properly.

Glaser Group was founded in 2019 by Maarten Glaser as a Costa del Sol real estate company. In 2025, we launched our holiday rental management division — a natural extension of what we were already doing for clients who kept asking the same question: “Now what do we do with it when we’re not here?”

Meet the founder

Maarten Glaser, founder.

Dutch by birth, Costa del Sol by choice. Maarten moved to Spain in 2017 and founded Glaser Group as a real-estate business in 2018. The rental-management division launched in 2025 — same hands-on operating philosophy, applied to short-term rental.

Why we started: the family kept getting asked the same question by friends and clients — who’s actually looking after the apartment when you’re not here? Most honest answers were “nobody we’d trust”. Glaser Holiday Rentals exists to be a different answer to that question.

Over time, a pattern emerged. Clients who’d bought through us kept coming back with the same next problem — their property needed to earn income between their own stays, but the rental managers they’d tried weren’t up to the job. Slow replies. Surprise fees. Reports that raised more questions than answers.

So in 2025 we launched Glaser Group’s rental management division — the service we wished existed for our own clients. GIPE (Gestor Intermediario de Patrimonio Edificado) and CEPI (Confédération Européenne des Professions Immobilières) accredited. Maarten speaks Dutch, English, Spanish and German — backed by a fully international team that looks after owners and guests end-to-end.

Why we exist

We’re building the rental manager
we’d want to hire ourselves.

Coín's rental market is materially different from coastal Costa del Sol — 101 registered VUTs, around 627 bed-places, and a long-stay-leaning rhythm. The town runs on British, Dutch and German pre-retirees taking 1-12 month bookings, with a smaller short-let layer in the centro histórico and on the rural fincas with private pools.

Most managers on the coast aren't set up for that mix. They run a summer-let playbook and try to apply it inland, where it doesn't fit. We work Coín deliberately — long-stay platforms (Idealista, Fotocasa) for the dominant tenant flow, Airbnb and Booking.com for the shoulder-season short-let around Caminito del Rey, and DAFO-status review for the rural fincas where irregular building status needs legalising before short-let licensing.

Where we land: a service designed for inland Guadalhorce reality. Not a coastal template forced onto a working Spanish market town.

“The owner’s peace of mind. The guest’s good experience.
Both, every time.”

How we work

Principles, not policies.

Six things that stay the same, at any size.

One point of contact

Every Coín owner gets a senior team member as their direct contact. The inland market — fewer, longer bookings, larger properties, DAFO-status checks on rural fincas — rewards continuity. Same voice at discovery, same voice on the December owner-statement query.

Honest numbers

Coín statements work differently from coastal short-let. Long-stay rental income separated from short-let, cleaning and turnover lower in frequency but higher per-visit. Every line itemised. The Saturday-market shoulder season and Caminito del Rey demand visible alongside the summer family-week revenue.

A good fit, both ways

Not every Coín property is right for short-let. Many rural fincas need DAFO legalisation before VUT licensing is viable. We coordinate that conversation with a local lawyer before signing any management contract — and we say no when the property doesn't fit. Honest opinions, given early.

Quality at every size

Coín is opening for select properties — not a hundred fincas. The standard we run on the first eight Coín onboardings has to be the same one we run on the fiftieth. That means every onboarding includes the upstream DAFO + water-rights + comunidad-status checks, not just the easy ones.

Guests matter too

Coín's long-stay guests stay 1-12 months. Short-let cultural-stay travellers stay 4-7 nights. The standard of care has to match the booking length: in-person check-in for every arrival, mid-stay services on long bookings, the Saturday-market guide and Caminito del Rey trailhead directions in every welcome pack.

Less paperwork for you

Junta de Andalucía VUT (declaración responsable under Decreto 31/2024), NRUA registration through the Land Registry, annual N2 filing, DAFO coordination for rural fincas, water-rights documentation where applicable, SES.HOSPEDAJES traveller-reporting — Coín has the most complex upstream paperwork of any inland town in our coverage. We handle it end-to-end.
