If you're considering only one night in Howth, I'd add another day or two! You'll quickly fall in love with Brian's place and this adorable sea town. (If anything stay for the seafood!!) We actually used Howth as our home base and conveniently took the train into Dublin for the day. You could easily do multiple day trips from this location. Brian's place is so comfortable with a cool and stylish touch and walking distance to the cliff walk, restaurants and shops. He met us when we first arrived and gave us great recommendations for Dublin as well as Howth. Brian even offered to chauffeur us to the airport in his Tesla for honestly what we would pay for a taxi - such a nice convenience! We can't speak more to the hospitality, delicious food and overall charm of Howth. Book it.
