Geraldine's house is a great place to stay - very clean, well kitted out, and in a great location, which is handy for the city centre but not so close to the pubs and bars that it gets noisy at night.
If you're using Google maps to get to Galway, be aware that the house's location is not accurate. Geraldine's directions are much better - 4th house with the green door after Joyce's supermarket (which has everything you could want and more!). The off street parking is great and felt very secure behind bolted gates.
I wouldn't hesitate to recommend Geraldine's place, we had a great time there!
