Dublin is quite small so it's probably not too far in distance to drive to the ferry port but it is a very busy city and the roads are always busy. Might be better to find somewhere to stay closer to the port. Sorry I can't be more helpful :)

Hi, depending how long you are there, you can buy a freedom travel pass, lasts for 72hrs from first use.includes the interlink bus from the airport and all Dublin buses also the hop-on hop-off tour bus. We didn't use the interlink bus as it was easier to catch the no.16 bus from stand 13 at the airport drops you off at Terenure Rd,(the driver will tell you where) then it's about 10-15 min walk to the b&b :)

if i remember correctly, about 20 rooms, maybe a few more. their website is off so i cannot confirm. it is not a kosher supervised b+b. they stock kosher breakfasts frozen and will heat and serve for you, and will probably do the same for lunches or dinners if you arrange in advance. the breakfast is not cheap but fair by the pries of local restaurants. i went to the supermarket and bought cornflakes. the rooms have a fridge and kettle.
