Our daughters (in their early twenties) travelled to Dublin and we found this tiny but cosy apartment of John's to them. The communication with John was perfect so we could be calm about the safety and availability of the accomodation. The room was not big but absolutely suitable for 3 of them and John provided decent amount and quality breakfast too. For them it was a bit cold but a heater was also provided - and this is something with the climate and habits so no complains. Just be prepared.
Thanks for the warm welcome, this apartment is a good choice if travelling on budget. It has a perfect location and very kind and reliable host.
