We arrived in Shannon at 9:30pm and our host sent me a detailed description of how to get to Limerick. Bus numbers, stops and fare prices. Since it was getting late her husband also came and picked us up at the bus stop so we wouldn't have to find the house in the dark.
We were given a key to get in the house and a packet of popular places to go and maps to get there. Pubs, grocery stores, restaraunts, etc.
The room was very comfortable and we had our own bathroom to use.
