To underline the point that you are unlikely to win RTB case in this instance. Tenant was advertising the flat on booking.com & even had the property owner replace mattresses when "guests" complained about beds.
Residential Tenancies Board says landlord should have issued warning notice to terminate the tenancy

Extract:
"A landlord who changed the locks of a Dublin 4 apartment after discovering her tenant was subletting it on an accommodation booking website was ordered to return rent paid and a €2,300 deposit by a Residential Tenancies Board tribunal last month.
The landlord explained how she encountered a cleaner entering the property on South Lotts Road “carrying lots of sheets and towels” in December, who informed her that she was preparing the property for the “next guest”.
During the hearing, the tenant repeatedly denied subletting the apartment noting that the property was advertised by someone with a different name."
"The tenant was seeking damages of €5,000, arguing that he was illegally evicted, alongside the return of his deposit and 10 days rent which he had paid until the end of December.
Noting the landlord’s “comprehensive evidence”, the tribunal was satisfied that the tenant did, in fact, sublet the property.
Although the tribunal found the tenant to be in breach of his obligations, the landlord should have issued a warning notice and the termination of the tenancy was therefore invalid, it said."
