If an accommodation states it is self catering it means it has kitchen facilities where you can prepare your own meals.

Ensuite simply means a private bath in the room.

Most prices are per person sharing unless stated otherwise.

You can get rooms with a phone in the room but keep in mind that even local calls are not free in Ireland. They are charged by the unit which is roughly 3 minutes and cost depends on the time of day and where you are calling, though this is changing so be sure to check. Calls outside Ireland are charged by the minute.

In Ireland price is not really an indication of quality. There are some beautiful places that cost very little and some higher priced that may not be all you expected. Over all though you are almost guaranteed clean, comfortable accommodations.
