Bob's place is in a really cute part of town, tucked away on a cul de sac that's close to the city center but also very near to Portobello and neighborhoods south of the city. If you go, definitely check out Fumbally Cafe just up the block :).
As far as amenities, it was super easy once I found their street. I was able to park my rental car out front, and the room itself was cozy and quiet. Bob's nephew, David, welcomed me to the house and gave me a ton of tips for things to do while I was in Dublin. I felt very comfortable there, and would recommend to anyone visiting the city.
