Classic, good old fashion B&B where the owners will be greeting you in person, not a box with some anonymous code for you to pick the keys from & check yourself out in the morning. A B&B where you’ll be asked about breakfast in the morning...
Conveniently located off the pick hours traffic routes I managed to get to UCD in 30 minutes (acceptable by Irish standard, exceptional for most EU capital)
Not a posh hotel, just a simple stay for any working class people (including Engineers ;-)
