The Dublin Region Homeless Executive has confirmed one of the city's largest homeless hostels is to close imminently.
The Brú Aimsir hostel on Thomas Street, operated by charity Depaul, provides emergency, overnight accommodation for up to 100 people.
The facility was initially opened in October 2015 as a temporary winter shelter for people sleeping rough.
A spokesperson for the DRHE said a final date for the hostel's closure had not been confirmed. However it is understood that the doors will close in the coming days.
The local authority said capacity has been sourced at three additional locations to replace the beds closing in Brú and there will be an overall increase in the number of available beds.
Those currently sleeping in the hostel, which is used on a "one-night only" basis, will be accommodated in new facilities.
It is understood that not all of the replacement beds will be available immediately and not all are based in the city centre.
Sinn Féin's housing spokesperson, Eoin Ó Broin, said it was concerning that the closure had been "deliberately kept out of the public domain".
"Will all of the people currently accessing emergency beds at Brú be accommodated later this week? If so where and when?", he asked.
The Dublin Mid-West TD also questioned whether those being relocated would have the same level of support currently being provided by Depaul.
The DRHE said some of the replacement beds would be in 24-hour facilities, compared to the overnight-only service currently available at Brú Aimsir.
