Long term parking for a car in Galway???

Has anyone got any good local knowledge into where to leave a car for an extended time. The thing is I have a car in Ireland but will be traveling for about 4 weeks in September and don't know what to do with my car, it will be in the Galway area. I don't rent a house or anything as I will have just finished a job near Clifdon and need somewhere safe and cheap to leave my car while away. Any ideas would be awesome as I am stumped on this one!

Thanks heaps,
Nicola
