The story in one line
Staycity Group operates aparthotels across Europe under the Staycity and Wilde brands. Guests reach out constantly, before booking, before arrival, mid-stay, across WhatsApp, website chat, email and OTA inboxes, in more than a dozen languages and from over ninety countries. D3x sits inside that flow and does the work: not a chatbot that answers, but AI Agents for Hotel groups that resolve requests and executes them in Staycity's operational systems.

01B: The company · Two brands, one ambition
Founded in Dublin in 2004, Staycity Group operates two complementary brands serving business and leisure guests staying a night, a week or a year.

Central, well-equipped apartments with hotel-standard service, the everyday backbone of the group.
City-centre · gym · lounge · 24h reception

Named for Oscar Wilde, the group's boutique lifestyle brand, with bespoke interiors and elevated F&B.
Design-forward · café-bar · co-working
+20 by 2030
Twenty new locations by 2030, the fastest-growing aparthotel chain in the EU.
An aggressive European pipeline. The question every scaling operator faces: how do you serve more guests, in more places, without ballooning cost?
The operating principle
Staycity is scaling toward 20 additional properties while keeping its Dublin HQ team flat, no new central hires to absorb the growth. That only works if each new property arrives with capacity built in. D3x is that mechanism: as the estate grows, guest conversations are absorbed by the same AI layer rather than by new coordinators, agents or night staff. The 55% WhatsApp autonomy rate is the unit economics of expansion.

02: The challenge · Before D3x
Extended-stay guests behave differently from hotel guests. They ask more, over longer windows, and expect a fast, human-quality answer at any hour. For Staycity, that demand landed simultaneously across WhatsApp, website chat, email and OTA inboxes, each a separate tool, each a separate queue.
The hard part was never writing a reply. It was that a real answer often required doing something: raising a housekeeping task, logging a maintenance fault, checking a booking, correcting an invoice. A conventional chatbot could acknowledge the request. It couldn't complete it, so the work still fell to on-property teams, at all hours, in every language a guest happened to write in.
Conversations by channel · August 2026
“Chatbots answer. D3x resolves.”
Staycity didn't need faster acknowledgements. It needed guest requests turned into completed work, inside the systems the property teams already run on.
Fragmented channels
Four inboxes, no single view of the guest.
Round-the-clock demand
More than a quarter of website conversations arrived outside staffed hours.
Multilingual load
Guests writing in 14 languages from 91 countries.
Answers that needed action
Replies alone left the operational work undone.
03: The solution · D3x in the loop
D3x unifies Staycity's guest channels behind a single AI layer, then wires that layer directly into the tools property teams use to get work done. A request doesn't stop at a reply, it becomes a task, a ticket, or a resolved answer, automatically.
01
WhatsApp, website chat, email and OTA inboxes converge into one AI-orchestrated flow, with full guest context carried across all of them.
02
The AI understands intent in the guest's own language and answers end-to-end, or drafts for a human when judgement is needed.
03
Where action is required, D3x creates the task directly in Optii or Snapfix, housekeeping, maintenance, ops, no re-keying.
“A request that used to sit in an inbox now arrives as a task the team can action, in the system they already work in.”
Connected systems
Guest requests become live housekeeping & service tasks across 29 connected properties, with the estate moving to Snapfix through September.
Live at Staycity Tivoli and Liverpool Waterfront since July, with normal operations in August. Remaining properties move from Optii to Snapfix in September.
Email enquiries drafted and resolved inside the existing service desk, ~6,400 AI-generated messages this month, led by Frankfurt, Heidelberg and Leipzig.
Integration updated so AI can reply directly to Booking.com messages; feature not yet active, pending Staycity IT support.

AI-only resolution rate, deeper integration compounds
Across 29 Optii/Snapfix-connected properties, housekeeping-wired sites resolve autonomously 11 points more often (56% vs 45%), evidence that D3x's advantage compounds the deeper it's integrated.
Always on
~800 website conversations and ~1,900 messages arrived outside staffed hours, and were answered anyway. Coverage doesn't clock off.
04B: The impact · Outbound WhatsApp
August introduced proactive WhatsApp templates at Staycity Tivoli, turning the group's highest-volume channel from inbox-only into a two-way relationship. ~2,500 outbound messages were attempted in the first month.

04: The impact · Work done & satisfaction
The point of resolving isn't a tidy transcript, it's operational work getting done. In August, D3x turned guest requests into ~4,800 housekeeping tasks inside Staycity's operational systems, while guests rated the AI's replies almost as highly as human replies.

The takeaway · Resolves, not routes
In one month, across 40 European properties, D3x held WhatsApp AI-only resolution at 55%, executed nearly five thousand housekeeping tasks, launched outbound WhatsApp at Tivoli, and earned guest satisfaction on par with the human team, in 14 languages, around the clock. That's the difference between a chatbot that answers and AI Agents for Hotel groups that resolve.
