Firstly don't confuse the location of this hostel, Newport for the Newport in Gwent, they'll no where near each other! This Newport is on the Pembrokeshire coastal path and is about five miles from Fishguard. The hostel has a car park and is 5 minutes from a street of shops, pubs and cafe's. Walking the other way brings you directly onto the coastal path and then along to the small beach area where there are more facilities and an great ice cream shop.
The hostel when we visited was being run by volunteers and so although they were helpful, knew nothing about the area since they were from Yorkshire. However, the hostel was converted from an old school in 1995, so everything is new and smart. The rooms are adequate and the showers hot and very powerful (I switched it on and was propelled into the corner of the shower cubicle!). This hostel is also self catering only but has a huge kitchen and with the local abundance of pubs and cafes, really only cooking breakfast is necessary.
A great hostel for families as there is plenty to do in the surrounding area, the beach, Castell Henllys (Iron Age village)is near by as is the ancient burial chamber Pentre Ifan.
