We stayed at An Maide Ban to rehearse our band before some live shows, and it was perfect...
We set up the 5 piece band in the roomy games room, with a PA, and went for it. It's far enough from other houses, and the walls are thick enough, that we didn't bother anyone with our noise!
The house has a separate sitting room, a well equipped kitchen, and three huge bedrooms. Worked a dream. We didn't really explore the surroundings, but had a great outdoor meal at the Errigal Hotel, about 10 minute drive. Clíona was incredibly helpful, even sourced us a bass amp when ours went down!
