The Coastguard station is 2 miles from the very good and pretty town of Clifden. It's on the lower sky road and very easy to find once you've checked it out first on google maps/earth.
We stayed in the only three bedroom rental there, and there are a number of other two bed options, with a very interesting one bed option in what's called, the Tower.
The three bedroom rental, has three good sized bedrooms, two of them have double beds and one of these has an en suite with shower. The third bedroom is a twin room. The room with en suite faces the ocean while the other two face the carpark.
Downstairs is open plan, where there is a large lounge/eating area and a well appointed kitchen. There is also a small back hall where the stairs is located and it is here that you can hang coats and store shoes/boots.
There is one bathroom upstairs (apart from the en suite) and yes, it has a bath + shower
Everything that I could think of was supplied with the house - EVERYTHING. There was even foil wrapping for our sandwiches. I brought tea towels and washing up liquid, there was no need, they were supplied. Lots of towels + spares are upstairs and also spare sheets. Soaps and toilet rolls are also supplied but not shower gels or other hygiene products.
The lounge has a selection of books, a TV(Irish terrestrial stations only) and a Radio. There is an open fire there and a starter pack of turf and firelighters. The kitchen has a good sized fridge with a freezer section and a dishwasher. Loads of crockery, cooking pots and cooking utensils are also provided. Washing machines are available in the separate 'laundry' building in the car park. If all the apartments were occupied, there may be a car parking issue, but when we stayed there (May) we had no trouble with parking. I believe there is room for about 5 cars to park comfortably, but more could be squashed in if required.
All of the appartments have some windows overlooking the beautiful bay below. Sleep quality was excellent as the building is not right on any road. I slept very well in any case !
The owner, Tommy, who restored the building very sympathetically about 15 years ago, lives nearby, just in case you have any problems or questions.
The only possible downside is that it is two miles from Clifden, however for some, this might not be a disadvantage at all ;-)) In our case, this was not an issue.
Whle we were there on our very short break, we climbed the Bens (16km away) and on the following day we cycled the Sky Road Loop on rented cycles which cost us 12 euro each per day.
