Easy to get to on foot (follow cycle path from Terminal 2), but I'd recommend catching the bus and taking a stroll in Santry Park if you want to stretch your legs. Also, be prepared to walk around several blocks of flats before you find the right one. The keypad to enter the code was broken when I arrived, but that wasn't Valentina's fault. I did, however, wonder how long I'd have to stand before somebody arrived to let me into the building. Check-in information provided at the last minute, very disconcerting for nervous travellers.
