Every day we seek a broad range of challenges. Dive into our diverse projects through our case-studies.
From a single apartment in Athens to a Hotel Group.

The Oniro Story

Started with a single apartment in Athens followed with a private house in Mykonos. Using those experiences to better understand the construction dynamics of Greece we expanded into a portfolio of luxury residential assets in Athens and then into a small boutique hotel in Mykonos, Oniro Suites where the Oniro Brand was born and developed in the following year into the Oniro Hotel group having in a short amount of time 3 hotels in operation and another 2 in under development. Dealing from identifying the real estate asset opportunity into a cost efficient but high-end construction and then to the details of the operation covering the whole business cycle the Oniro story embodies our approach to how we approach investments and create value.

The property has undergone a complete renovation and was converted into a luxury boutique hotel of 8 suites. Oniro Suites opened in June 2018 and finished the year with close to full occupancy, excellent client reviews and very high ADR numbers
