The TMR Hotel Collection, owned by Austrian investor Thomas Röggla, is to re-open its hotels from June 29.
The group's 13 hotels across the country include Harvey's Point in Donegal and the Connemara Coast Hotel in Galway, both acquired over the past two years.
Its portfolio also includes the Farnham Estate in Cavan and Mount Wolseley Estate in Carlow as well as Aghadoe Heights Hotel in Killarney and the Diamond Coast Hotel in Sligo.
The group's Plaza Hotel in Tallaght, which is currently undergoing a multi-million euro refurbishment, will re-open later in the year.
TMR said it is taking all necessary measures to ensure the safety of guests and staff while also ensuring an exceptional hospitality experience.
"Best practice health, safety and hygiene protocols are being implemented in line with World Health Organisation, the Health Service Executive and Government directives," the hotel group said.
The group said it has also developed an industry leading protocol which combined with using hospital grade products and PPE, will assist in protecting the safety of guests and staff.
Eimear Fox, Director of TMR Hotel Collection and Davy Real Estate, said that since news of the easing of restrictions it has seen a notable uptick in traffic to our websites.
"Given ongoing international flight restrictions almost all inquiries are from domestic holiday makers, with good demand in particular for our hotels in popular regional locations such as Sligo, Donegal, Cavan, Carlow and Galway," Ms Fox said.
She also said the group has been very busy rescheduling many weddings at its hotels.
"We look forward to a time when, pandemic-conditions permitting, we will have greater certainty regarding the timing and the size of weddings," she said.
"In the interim we are very much summer and Covid-ready with hospitality, health and safety very much at the centre of how we operate," she added.
