We had a fantastic visit and it was our first overnight stay in Athlone ever. Athlone really punches above it's weight for a small town. There is a real buzz about the place. The location couldn't be better with a fantastic view of the river Shannon. It was so easy to pop across the bridge to the recommended parking (€15 for 5 days) not far from the castle. As far as things to do the castle itself was well presented and the biking river cruise is recommended. Our teens enjoyed BaySports and Tayto park which is just 90 minutes away. The apartment itself was clean, spacious, and perfect for a family with 2 teens. The kitchen had everything we needed to enjoy a meal or takeaway and the TV was handy for a movie at the end of the day. I would highly recommend and stay here again.
