Mike's house has been really useful to us when we moved to Galway. While they were not in the city during our stay, there were no communication issues or no check-in / check-out issues. There were clear instructions given or left in the house.
Aldi, Lidl and Dunnes are at walking distance so you won't feel hungry. Boots too for those flu medecines.
Lot of toys and books in the house for kids.
If you fancy the city life, you'll need a car or take the bus. There is a Gocar spot near the shopping center which we used, great if you need a car for a few hours.
There's also an indoor playground in walking distance, great to entertain small kids too during rainy days.
We also easily extented our stay for a few more nights with Mike.
