We recommend Sean's apartment, especially apt. #1 with the beautiful view of the bay. The beds are comfy, there is plenty of hot water, good wifi, and the basic tv channels are available. Sean and Cathal had excellent communication with us. The Salthill location with the nearby promenade is excellent for walking both into Salthill and to Galway town. The northeast route to town takes about 25 minutes. Tesco grocery is a 10 minute walk and Morton's is about 3 minutes away. There are lots of restaurants (we liked the Gourmet Food Parlour and O'Reilly's Kitchen) and O'Connor's pub in the Salthill neighborhood.
The only disadvantage to this place is the locked entry gate that some careless residents noisily bang shut. Not too disturbing during the day, but more problematic in the night.
