We had a lovely stay in Letterfrack. The apartment fulfils the basic needs for your stay and is located in the centre of the village. The apartment is a bit old, but it functions as a good place if you're planning to only sleep over while exploring Connemara the rest of the day.
Apart from the couch (which was worn/torn and was covered up with a cloth), the apartment is exactly like in the pictures. Unfortunately the living area and hallways were not cleaned well, but the bedrooms and bathroom were cleaned properly.
Overall recommended if you want to have a good apartment in a nice idyllic village.
