It would be a great hotel except for very basic problems. Toilets do not flush well. The heat is either blasting or off. No control of temperature. They have that old UK separate hot and cold faucets. It's a small room in addition.

The hotel is located in a nice, quiet but convenient location close to restaurants and within walking distance (20-30 mins) of downtown Dublin attractions. Valet parking was convenient. Room was delightful and comfortable. Nice bar and breakfast.
