The location is close to the Centre. I was traveling by car and there was no problem to find where the Hotel was located and there was a Public Carpark a few hundred meters from the hotel, next to the channel/water.
The support from the Staff was brilliant when I checked in. They asked about where I had parked the car and I could get a discount for one night, 4 Euros.
The room was marv! I couldn´t ask for more than the water pressure in the shower was hard to figure out.
Otherwise, when I return to Waterford for the Viking Museum, I´ll stay at The Granville.
