If you want to be within 10 mins walk of downtown Dublin this is the place for you. As a 70 yr old couple we walked into Dublin every day though if you are younger you may choose the hire bikes right outside the apt. Though you would need to be up early as I was amazed at how quickly they went out in the morning, even when a truck load arrived and filled the rack again.
This a very old Georgian building with offices on the grd flr and apts above, Jame’s apt is comfortable with everything as listed available.
Another suggestion is to do a hop on hop off tour to see around Dublin though this could take a few hours it is a good way to get an overview. You don’t need a second day as it is quicker to walk around, very busy traffic even google times have walking quicker than cars or public transport. The choice of public transport is buses, trains or tram. Even taxis are easy and very polite and helpful.
