Hi Aine.
Thanks for letting us stay in your apartment for our time in Dublin.
We were a bit confused at first in getting the keys but found them eventually.
On the shower and timer - it may be good to leave a note to let residents know about the timer and likely hours when hot water will be available. We didn't get this right at first but also got it right eventually.
Thanks again and we will be sure to contact you again when in Dublin again.
